- Your first task in solving any projectile problem is to determine which case you are dealing with, and that lets you know what equations to use. Case 2 has its own special equations. Case 3 usually involves determining the vertical and horizontal components of the launch velocity. If you know the horizontal velocity and time, R=Vht works for any case of equation.You throw an object directly up into the air and then catch it when it comes back down. It hits your hand at a speed of 7 m/s on the way down. What was the initial velocity of the ball? Use a kinematic approach.An athlete has an intuitive knowledge, gained by experience, of the changing nature of a ball in flight. If the athlete ignores the effects of air, the x-component of the velocity changes by the same amount each second. True or False?
- 7. You are sitting in a helicopter that is climbing directly upward at a constant velocity of 2.5 m/s. The helicopter door is open, and you notice that a small screw slips out the door. You can assume the screw has no horizontal component to its velocity. (a) What is the velocity of the screw 4.0 s after falling out of the helicopter? (b) How far below the helicopter is the screw at this time?A dog is chasing a cat, which is chasing a mouse. All of the animals are moving in one dimension. The mouse is in the lead, moving at 3.84 m/s . The cat is in the middle moving at 1.58 m/s.The dog is in the back moving at 3.27 m/s. All velocities are relative to the ground what is the velocity of the dog from the perspective of the mouse.A batter hits a fly ball with an initial velocity of 37 m/s at an angle of 32° from the horizontal. How much time does the outfielder have to get to the appropriate position to catch the ball?
- 11.A blue person throws an object with an initial velocity of 25.0 m/s at an angle of 37.0°. A green person stands 15.0 meters in front of the blue person and throws an object straight up. Assume that both objects are thrown from the same initial elevation. a) If the green person throws their object with an initial speed of 20.0 m/s, at what time should they throw it such that it strikes the other object while it is traveling upward? Measure this time relative to when the blue person throws their object? b) If both people throw their objects at the same time, with what initial speed must the green person throw their object such that they collide? Answers: a) ~0.267 s b) ~15.0 m/sJenny and Betty are having a great time at Busch Gardens riding the Ubanga Banga bumper cars. Jenny, who is traveling southward in her bumper car, aims her car toward Betty, who is traveling northward in her bumper car. The cars collide and briefly come to a stop. What is the direction of the acceleration of Jenny's car during the collision?Dylan and Sophia are walking along Bluebird Lake on a perfectly calm day. Dylan, determined to impress Sophia by his ability to skip rocks, picks up the flattest rock he can find and gives it a sidearm launch from the edge of the water. The rock acquires a completely horizontal speed of 27.2 m/s from a height of 0.54 meters above the water surface. How much time does it take to hit the surface of the water?
- Billy-Joe stands on the Brooklyn Bridge kicking stones into the water below. If Billy-Joe kicks a stone with a horizontal velocity of 3.50 m/s, and it lands in the water a horizontal distance of 5.40 m from where Billy-Joe is standing, what is the height of the bridgeA playful cat sees a mouse run past him with a constant velocity of 2 m/s. One second after the mouse passes the cat, the cat jumps after the mouse at an angle of 30 degrees and some unknown initial velocity. Being a naturally-talented cat, he lands perfectly right where the mouse ends up (the mouse didn't think to turn or change his speed). How much time does the cat spend in the air?A gannet is a seabird that fishes by diving from a great height. If a gannet hits the water at 32 m/sm/s , what height did it dive from? Assume that the gannet was motionless before starting its dive.
