You push a box of mass 20.6 kg with your car up to an icy hill slope of irregular shape to a height 4.3 m. The box has a speed 12.3 m/s when it starts up the hill, the same time that you brake. It then rises up to the top (withno friction) to a flat area before sliding into a box larger box of mass 19 kg. The boxes then fall off a sheer cliff together to the ground (with no drag).What is the path basis just before impact?ŷ +父+%3D

Given mass(m1)=20.6kg height=4.3m U1=12.3m/s m2=19kg

A lightweight drone (1.00 kg) is launched at 800 m high and moves upward at a constant velocity (whileignoring the effects of gravity only on the drone). The balloon, when measured at a horizontal distance fromyou, is about 1600 m away from you. At the moment when the drone moves, you shoot a bullet (weight =180g) with an initial velocity of 1009 m/s at a fixed angle α, where sin α=3/5 and cos α= 4/5. (g = 9.8 m/s2) d. Provided that the collision is inelastic, calculate the speed after the collision.e. Calculate the height the two objects taken from the impact up to the maximum height before it startsfalling to the ground.
A 0.525-oz model rocket is launched vertically from rest at time t = 0 with a constant thrust of 0.9 lb for 0.3 s and no thrust for t > 0.3 s. Neglect air resistance and the decrease in mass of the rocket. Find the time required to reach the maximum height
A basketball player drops a 0.5 kg basketball vertically so that it is traveling at 5.0 m/s when it reaches the floor. The ball rebounds upward at a speed of 3.2 m/s. The ball is in contact with the ground for a time of 10 ms. Draw a velocity vs time graph for the ball and an impulse-momentum bar chart where the initial state is right before the ball hits the ground and the final state is right after the ball hits the ground.
In a 300-rough incline, a 1.25 kg block is initially at rest beside a spring that is compressed by 24 cm as shown in the figure below. The spring has a spring constant of 180 N/m and the coefficient of sliding friction between the incline and the block is 0.23. When the spring is released, (a) how far up the incline (with respect to its initial position) will the block slide before sliding back? (b) What is the speed of the block at the instant it is 0.34 m from its initial position?
