Consider two cases in which cart A moves to the left with momentum \vec{p}_ip β i and then collides with a second cart which is initially at rest on a horizontal, frictionless air track. In case 1, cart A moves to the left after the collision at a speed of 1 m/s. In case 2, cart A moves to the right after the collision with the same speed as in case 1 (1 m/s). After the collision, the magnitude of the second cart's momentum in case 1 is the magnitude of the second cart's momentum in case 2.

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:

The protons in a nucleus are approximately 2 β 10^β15 m apart. consider the case where the protons are a distance d = 1.93 β 10^β15 m apart. calculate the magnitude of the electric force (in n) between two protons at this distance.
