A mountain climber stands at the top of a $50.0-\mathrm{m}$ cliff that overhangs a calm pool of water. She throws two stones vertically downward $1.00 \mathrm{~s}$ apart and observes that they cause a single splash. The first stone had an initial velocity of $-2.00 \mathrm{~m} / \mathrm{s}$. (a) How long after release of the first stone did the two stones hit the water? (b) What initial velocity must the second stone have had, given that they hit the water simultaneously? (c) What was the velocity of each stone at the instant it hit the water?

The coefficient of static friction is 0.672 between the two blocks shown. The coefficient of kinetic friction between the lower block and the floor is 0.111. Force F causes both blocks to cross a distance of 6.77m, starting from rest. What is the least amount of time in which the motion can be completed without the top block sliding on the lower block, if the mass of the lower block is 1.72kg and the mass of the upper block is 2.69kg

The velocity-time graph of a particle moving along the x-axis is shown. The particle has zero velocity at t = 0.00 s and reaches a maximum velocity, vmax, after a total elapsed time, t total. If the initial position of the particle is x0 = 5.30 m, the maximum velocity of the particle is vmax = 34.1 m/s, and the total elapsed time is t total = 25.7 s, a) what is the particle's position at t = 17.1 s? b) At t = 17.1 s, what is the particle's velocity? c) At t = 17.1 s, what is the particle's acceleration?
