An athlete performing the long jump tries to achieve the maximum distance from the point of takeoff to the first point of touching the ground. After the jump, rather than land upright, she extends her legs forward as in the photo. How does this affect the time in the air? How does this give the jumper a longer range?
A hammer of mass m = 0.475 kg is moving horizontally at a velocity of v = 5.5 m/s when it strikes a nail and comes to rest after driving the nail a distance Δx = 1.15 cm into a board. 1. What is the duration of the impact, assuming the acceleration is constant during this time period, in terms of the given variables?

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?
Dominador, who is standing on the edge of an 80-m tall cliff facing the sea, kicks a ball horizontally at a speed of 13.01 m/s. How far from the base of the cliff will the ball hit the sea water? Let be the initial vertical position of the ball, with positive position in the upward direction. The vertical displacement of the ball from the edge of the cliff to the seawater is: meters. The time it takes for the ball to reach the seawater is: t = seconds. The horizontal distance traveled by the ball is: meters.
Two kittens are running toward each other, one is named Chloe and the other is named Luna. Luna runs at a speed of 1.90 m/s. If Chloe jumps at an angle of 14.0° with speed 2.80 m/s, at what distance from Luna should Chloe jump to make sure she lands on Luna?
Jonah is reading a novel that describes an athlete participating in an archery competition. The athlete is 186 cm tall and hits an amazing shot where they fire the arrow completely horizontally and it lands 51 m away from them. 1) neglecting air resistance and drag, what must the initial speed of the arrow be? 2) if the arrow was instead fired at an angle of 45°, how far would it have travelled if it was launched at 187m/s?
A javelin thrower standing at rest holds the center of the javelin behind her head, then accelerates it through a distance of 70 cm as she throws. She releases the javelin 2.0 m above the ground traveling at an angle of 30 degrees above the horizontal. Top-rated javelin throwers do throw at about a 30 degree angle, not the 45 degree you might have expected, because the biomechanics of the arm allow them to throw the javelin much faster at 30 degrees than they would be able to at 45 degrees . In this throw, the javelin hits the ground 64 m away. What was the acceleration of the javelin during the throw? Assume that it has a constant acceleration.
Why is the following situation impossible? Emily challenges David to catch a $1 bill as follows. She holds the bill vertically as shown, with the centerof the bill between but not touching David’s index finger and thumb. Withoutwarning, Emily releases the bill. David catches the bill without moving his hand downward. David’s reaction time is equal to the average human reaction time.

The record distance in the sport of throwing cowpats is 81.1 m.m. This record toss was set by Steve Urner of the United States in 1981 . Assuming the initial launch angle was 45∘45∘ and neglecting air resistance, determine (a) the initial speed of the projectile and (b) the total time the projectile was in flight.
A projectile is fired at time t = 0.0 s, from point 0 at the edge of a cliff, with initial velocity components of vox = 40 m/sand voy = 600 m/s. The projectile rises, then falls into the sea at point P. The time of flight of the projectile is 150s. the x-coordinate of the projectile when its y-component of velocity equals 480 m/s upward is closest to:
Georgia, standing on the back of the pick-up truck, wants to throw her last piece of balut to her mortal enemy, Emma. before the truck started moving, the two women are separated by a distance of 2 m. For two seconds, the truck uniformly accelerated until it reached a velocity of 4 m/s which it then maintained. With hatred, Georgia throws the last piece of balut with a velocity of 12.5 m/s at an angle of 40° from horizontal, measured relative to the truck. If she makes the throw 2.8 seconds after the truck started moving, will she be able to hit Emma? Note that Emma is at rest due to exhaustion from their earlier fight and she cannot dodge the balut. Set your origin at point A. Neglect air resistance.
