1.Using Calculus Derive W_ext=1/2mv_f^2-1/2mv_i^2 2. An athlete jumping vertically on a trampoline leaves the surface with a velocity of 8.5m/s upward. What maximum height does she reach on Earth?(g=9.8m/s) 3. Define force causing centripetal acceleration.
The maximum height above the ground for a gymnast jumping straight upward with an initial speed of 5 m/s is O a. d) None of the above lon O bc) 5 m Ocb) 2.5 m O d. a) 1.25 m
the height above the ground of a child on a swing varies from 0.5m at the lowest point to 2.0m at the highest point. what is the maximum speed of the child?
Spider-Man launches himself from the ground so that he travels vertically upward, eventually catching hold of a hovering helicopter that is 420 m above the ground. Assume air resistance is negligible as he ascends. (g = 9.8m/s) » What minimum initial takeoff speed must Spider-Man have to reach the helicopter?
A girl of mass m1=60.0 kilograms springs from a trampoline with an initial upward velocity of vi=8.00 meters per second. At height h=2.00 meters above the trampoline, the girl grabs a box of mass m2=15.0 kilograms. (Figure 1) For this problem, use g=9.80 meters per second per second for the magnitude of the acceleration due to gravity. A girl of mass m1=60.0 kilograms springs from a trampoline with an initial upward velocity of vi=8.00meters per second. At height h=2.00 meters...
A 50-kg athlete jumps on a trampoline hitting it vertically downward with a speed of 2 m/s. If the athlete remains in contact with the trampoline for 0.1 s and the trampoline exerts an average upward force of 2500 N on her, calculate the maximum height she can reach after leaving the trampoline. A. 0.45 m B. 1.20 m C. 0.20 nm D. 0.80 nm E. 0.15 m
A football quarterback is moving straight backward at a speed of 3.9 m/s when he throws a pass to a player 15m (10%) Problem 9: straight downfield 33% Part (a) If the ball is thrown at an angle of 25. relative to the ground and is caught at the same height as it is released, what is its initial speed relative to the ground in m/s? її 33% Part (b) How long does it take to get to the receiver...
You throw a 20-N rock vertically into the air from ground level. You observe that when it is a height 15.9 m above the ground, it is traveling at a speed of 24.8 m/s upward. A.Use the work-energy theorem to find its speed just as it left the ground. B.Use the work-energy theorem to find its maximum height.
A football quarterback is moving straight backward at a speed of 1.5 m/s when he throws a pass to a player 24.7 m straight downfield. If the ball is thrown at an angle of 33.2 degree relative to the ground and is caught at the same height as it is released, what is the ball's initial speed relative to the ground?
A coin is tossed upward from an initial height of 7 m above the ground, with an initial speed of 7.4 m/s m/s. The magnitude of the gravitational acceleration g = 9.8 m/s2 Take the point of release to be y0 = 0. Choose UPWARD as positive y direction. Pay attention to the signs of position, velocity and acceleration. Keep 2 decimal places in all answers. (a) Find the coin’s maximum height in meters above the ground? m Correct (100.0%)...
