"Nate throws a ball straight downward, letting it bounce once before catching it. (we can ignore air resistance)
A. what is true about the acceleration AND the velocity of the ball on its way down?
(assume upward is a positive direction)
1. Acceleration increases and velocity is negative and thus decreasing
2. Acceleration remains constant and velocity is negative and thus decreasing
3.Acceleration is decreases and velocity is positive and increasing
4. Acceleration remains constant and velocity is negative and decreasing
(What of the four suggestions is correct?)

Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
