11. A disgruntled student in the back row of 1510 wishes to hit the professor standing at the front of the class in the back of the head with a spit ball. The professor stands 2 meters tall and the spit baller is sitting in an elevated seat, 5 meters above the floor the professor stands on. The horizontal distance from the spit baller to the professor is 12 meters. The time of flight of the spit ball is 0.8 seconds given an initial spit ball speed of 15m/s. Find the velocity of the spit ball when it is fired.

Free Fall. Allan is on the ground YA,0 = 0 [m], and Bob is directly above him at YB,0 = 172.[m]. Bob drops a cannonball at the same time Allan shoots a similar cannonball directly upward. Allan’s cannonball was launched with enough speed so that both cannonballs will collide just as Allan’s cannonball reached its maximum height. What is the initial speed of Allan's cannonball ?
A seagull flies at a velocity of 12.5 m/s relative to the air straight into the wind. vSA = 12.5 m/st = 16 mind = 5.8 km 1. If it takes the bird 16 min to travel 5.8 km relative to the Earth, what is the velocity of the wind, in meters per second, relative to the Earth? Take the direction of travel of the seagull to be positive. 2. If the bird turns around and flies with the wind, how long, in minutes, will it take to return 5.8 km?
A cannon is on the edge of a vertical cliff 50 m high. The cannon then fires horizontally giving the cannon ball a speed of 420 m/s. What is the speed of impact (in m/s) of the cannon ball? O 420. O 423. O 432.

A man in the back row of 1510 of a theatre wishes to hit a statue in front of the theatre screen with a ball. The statue stands 2 meters tall and the baller is sitting in an elevated seat, 10 meters above the floor the statue stands on. The horizontal distance from the spit baller to the statue is 10 meters. The time of flight of the spit ball is 0.6 seconds given an initial ball speed of 15m/s. Find the velocity of the ball when it is fired.

A boy tossed the basketball at an angle of 38-degrees from the horizontal. The basketball is 1.6 m above the ground at the time of release and the basketball hoop is 6.4 m away and 3.6 m high. Neglecting the size of the ball in the calculation, determine the speed which the ball pass through the hoop. Answer in two decimal places. Numerical values only. Don't indicate units here, just on the submitted solution.
ASK YOUR TEACHER To improve your basketball skill, you attempt to toss your keys onto your desk each time you return to your dorm room. As shown in the figure, the keys leave your hand yo= 2.29 meters above the floor traveling at an angle 8 = 12.9 degrees above the horizontal. The keys land exactly in the middle of the desk (Ydesk = 0.93 meters high and Xdesk 3.36 meters away). %=? Yo Calculate all the following: The initial velocity, vo. of the keys? | The time they were in the air? meters/second seconds t=? York MY NOTES
Daniel takes his two dogs, Pauli the Pointer and Newton the Newfoundland, out to a field and lets them loose to exercise. Both dogs sprint away in different directions while Daniel stands still. From Daniel's point of view, Newton runs due North at 4.65 m/s, but from Pauli's point of view, Newton appears to be moving at 2.10 m/s due East. What must Pauli's velocity relative to Daniel be for this to be true? Express your answer in terms of the x- and y-components if North is the +y-direction and East is the +x-direction. x-component: m/s Y-component: m/s Express your answer as a magnitude and an angle measured counter-clockwise from due East. magnitude & direction: at a angle counter-clockwise from due East
You've told your friends and family that despite circumstances you are getting plenty of exercise by practicing basketball alone or with social distancing. In actuality you are merely throwing wadded paper toward the trash can while binging Netflix . The paper wad leaves your hand yo= 1.92 meters above the floor traveling at an angle 8 = 19.8 degrees above the horizontal. It lands exactly in the middle of the track can (Ytrash 1.16 meters high and Xtrash = 4.85 meters away). THROW Yo Calculate all the following: Vo=? 6 The initial velocity, vo, of the paper wad?
