After a 70 kg person steps from a boat onto the shore, the boat moves away with a speed of 0.7 m/s with respect to the shore. If the same person steps from the shore onto the boat, the person and the boat move away from the shore with the speed of 0.5 m/s. Assume that the initial speed of the person with respect to the shore is the same in both cases and that the person is moving in a horizontal direction. (a) Draw impulse-momentum bar charts for both situations. (b) Determine the mass of the boat and the speed of the person.

A 121 kg crate is sitting at the top of a ramp, which is inclined at an angle of 18 degrees with respect to the horizontal. The crate is a height 0.51 m from the ground, measured vertically from the ground to the crate. Someone gives the crate a quick shove to get it moving, after which it slides down the ramp without any further assistance. The coefficient of kinetic friction between the crate and the ramp is Hs = 0.23. How much time (in seconds) does it take for the crate to get to the %3D base of the ramp?
Water leaves a fireman’s hose (held near the ground) with an initial velocity v0 = 23 m/s at an angle θ = 33° above horizontal. Assume the water acts as a projectile that moves without air resistance. Use a Cartesian coordinate system with the origin at the hose nozzle position, as shown. Using v0, θ, and g, write an expression for the time, tmax, the water travels to reach its maximum vertical height. tmax =
you go on a trip on Mars. You toss a coin from an initial height of 0.855 m (about waist height) upward and observe that it takes 1.00 s for the coin to hit the ground with a speed of 2.71 m/s. What is the g- value on Mars and the initial velocity of the coin?
A riverboat took 2 hours to travel 24 km down a river with the current and 3 hours to make the return trip against the current. Find the speed of the boat in still water and the speed of the current.
Georgia, standing on the back of the pick-up truck, wants to throw her last piece of balut to her mortal enemy, Emma. before the truck started moving, the two women are separated by a distance of 2 m. For two seconds, the truck uniformly accelerated until it reached a velocity of 4 m/s which it then maintained. With hatred, Georgia throws the last piece of balut with a velocity of 12.5 m/s at an angle of 40° from horizontal, measured relative to the truck. If she makes the throw 2.8 seconds after the truck started moving, will she be able to hit Emma? Note that Emma is at rest due to exhaustion from their earlier fight and she cannot dodge the balut. Set your origin at point A. Neglect air resistance.
When serving, a beach volleyball player strikes the volleyball (mass = 265 g) at a height of 2.4 metres above the ground. The ball follows the standard path of a projectile, first rising as it passes over the net, and then descending. The opponent receives the volleyball 1.1 seconds later at the same height (2.4 metres above the ground), and at a horizontal distance of 13.5 metres from the server. Answer the following questions assuming there is no effect of air resistance. When the ball was received by the opponent, the horizontal component of velocity (in m/s) was? The vertical component of velocity at take-off and impact (in m/s) can be solved by recognizing that the vertical component of velocity at the point of maximum height in the trajectory of motion is (in m/s)?
