help A 0.20 kg ball is thrown straight up into the air with an initial speed of 17 m/s. Find the momentum of the ball at the following locations. (a) at its maximum height kg-m/s (b) halfway to its maximum height kg-m/s
A 0.11 kg ball of dough is thrown straight up into the air with an initial speed of 17 m/s. The acceleration of gravity is 9.8 m/s 2 . What is its momentum halfway to its maximum height? Answer in units of kg m/s.
A ball is thrown straight up with an initial speed of v m/s. The ball was released 1.2 m above the ground, but when it returns back down, it falls into a hole 14.2 m deep. If the ball’s speed at the bottom of the hole is 28 m/s, what was the initial speed v (in m/s) of the ball?
A ball is thrown straight up with an initial speed of 13.7 m/s. At what height above its initial position will the ball have one‑half its initial speed?
A ball is thrown straight up. It passes a 2.00-m-high window 7.50 m off the ground on its path up and takes 0.312 s to go past the window. What was the ball's initial velocity? Next, consider only the distance from the ground to the bottom of the window, and solve for the initial velocity using the velocity at the bottom of the window as the final velocity.
A ball is thrown straight up with an initial speed of 14.3 m/s. At what height above its initial position will the ball have one-half its initial speed? height:
A cat's crinkle ball toy of mass 35 g is thrown straight up with an initial speed of 7 m/s. Assume in this problem that air drag is negligible. (a) What is the kinetic energy of the ball (in J) as it leaves the hand? (b) How much work is done (in J) by the gravitational force during the ball's rise to its peak? (c) What is the change in the gravitational potential energy of the ball (in J) during...
A ball is thrown straight up in the air with an initial speed of 40 m/s. Ignore air resistance and take g - 10m/s2. What is the speed of the ball when it reach 40 m above the ground? 20 m/s 2012 m/s 2/20 m/s 3720 m/s 20/3 mis
A ball thrown straight up at ground level passes a height of 84 m in 6.3 s. The acceleration of gravity is 9.8 m/s 2 . What was its initial speed? Answer in units of m/s.... The answer is not (40.57)!!!!!
