A ball of mass, m is thrown straight up and rises h after leaving your hand, it momentarily stops. Acceleration due to gravity g is downward. Ignore air resistance.
Part A (5 points): If the ball is the system, and the Earth is the surroundings, what is the change in potential energy, ΔUsys of the system, and what is the work done, Wsurr by the surroundings ?
Δ Usys = 0; Wsurr = -mgh
Δ Usys = mgh; Wsurr = -mgh
Δ Usys = mgh; Wsurr = 0
Δ Usys = 0; Wsurr = 0
Δ Usys = -mgh; Wsurr = 0
Part B: If the ball + Earth is the system, and nothing is in the surroundings, what is the change in potential energy, ΔUsys of the system, and what is the work done, Wsurr by the surroundings ?
Δ Usys = 0; Wsurr = 0
Δ Usys = mgh; Wsurr = -mgh
Δ Usys = mgh; Wsurr = 0
Δ Usys = 0; Wsurr = -mgh
Δ Usys = -mgh; Wsurr = 0

A ball is thrown straight up with an initial speed of 19 m/s.
The ball was released 6.3 m above the ground, but when it returns
back down, it falls into a hole d m deep. If the ball’s speed is
35.7 m/s at the bottom of the hole, how deep is the hole (in
m)?
a ball thrown straight up returns to its starting height in 7.2s.its initial speed was----------m/s.

A ball of mass m is shot straight up into the air by a
spring-loaded launcher. Initially, the spring is compressed by a
distance D. After the spring is released, the ball has a velocity v
out of the launcher and finally reaches a maximum height H.
Ignoring air resistance, which of the following statements are
true?
True False If the spring constant is doubled, the
ball will max out at height 8H
True False The initial potential energy of the spring...

A ball of unknown mass m is tossed straight up with initial
speed v. At the moment it is released, the ball is a height h above
a spring-mounted platform, as shown in the figure below. The ball
rises, peaks, and falls back toward the platform, ultimately
compressing the spring a maximum distance d from its relaxed
position. Assume that the spring is perfectly ideal with spring
constant k, and that the mass of the spring and platform is
negligible....

A tennis ball is thrown against a wall and rebounced. M(mass of
wall)*v (for ball) =2*m(mass of ball) * V(for wall), KE(wall)=1/2 *
Mv2; KE(in)=1/2 *mV2 and
KE(out)=1/2 *mV2+1/2*Mv2 ; If
KE(in)=KE(out), Where did 1/2*Mv2 go? Is the KE
conderved? Prove it.

A spring-loaded toy gun is used to shoot a ball of mass
m=1.50kg straight up in the air, as shown in (Figure 1) .
The spring has spring constant k=667N/m. If the spring is
compressed a distance of 25.0 centimeters from its equilibrium
position y=0 and then released, the ball reaches a maximum
height hmax (measured from the equilibrium position of the
spring). There is no air resistance, and the ball never touches the
inside of the gun. Assume that...
