Draw a picture and show all work! A small airplane is flying due east with a speed of 37.0 m/s with respect to the air. The wind is moving with a speed of 18.0 m/s at an angle of 21.0 degrees north of due west (in other words, the wind is moving in a northwest direction, but more west than north). What is the speed of the airplane with respect to the ground?
You are jumping on a trampoline. Curious about how fast you are moving just as you liftoff the surface of the trampoline, you decide to make some measurements. You find ittakes your feet 1.5 s to get to their peak height above the trampoline surface. How fastwere you going as you left the surface of the trampoline? Assume negligible airresistance. Show your reasoning and all work.

(Do not type the unit in your answers) A new circus act is called the Texas Tumblers. Lovely Mary Belle swings from a trapeze, projects herself at an angle of 53°, and is supposed to be caught by Joe Bob, whose hands are 6.1 m above and 8.2 m horizontally from her launch point. You can ignore air resistance. a. What initial speed v, must Mary Belle have just to reach Joe Bob? Ans.: m/s b. What is the X-component of her velocity when Mary Belle reaches Joe Bob? Ans.: m/s c. What is the y-component of her velocity when Mary Belle reaches Joe Bob? Ans.: m/s
A projectile is fired from the ground (you can assume the initial height is the same as the ground) in a field so there are no obstacles in its way. It is fired at an angle 36° with respect to the horizontal and with an initial speed of 41 m/s. Air resistance is negligible in this situation. Call up the positive y direction, and toward the wall the positive x direction. ALREDY SOLVED PORTION: What is the maximum height that the projectile reaches? (30 m) What is the speed of the projectile at its maximum height? (33 m/s) What is the earliest time when the height of the projectile is half of its maximum value? (0.72s) NEEDS SOLVED: 1.The same projectile was then fired in the same way toward a wall that is a horizontal distance 109.1 m from where the projectile was fired.What was the height of the projectile when it hit the wall? 2. What was the velocity of the projectile when it hit the wall? 3.What was the speed of the projectile when it hit the wall?
