- A 40 kg ball moving to the right at 5.0m/s collides head-on with the stationary 2.0 kg ball. If the collision is elastic, determine the direction and speed of each ball after the collision.6. A7.0 g bullet is fired into a 1.5 kg block and becomes embedded in the block. After the collision, the block slides 2.80 m up an incline of 30 degrees with a surface that has a coefficient of kinetic friction of 0.25. How fast was the bullet traveling prior to striking the block?An archer shoots an arrow toward a 300-g target that is sliding in her direction at a speed of 2.25 m/s on a smooth, slippery surface.

- A homogeneous pulley with two grooves consists of two wheels which turn together as one around the same axis. The moment of inertia of the two wheels together is ICM = 40 kg m2. The radii are: R1 = 1.2 m and R2 = 0.4 m. The masses that hang on both sides of the pulley are m1 = 36 kg and m2 = 12 kg. We will assume that the masses of the ropes are negligible. Determine the angular acceleration of the pulley, acceleration of the masses, and the tensions of the ropes.A person with a mass of 50 kg is driving her car at a velocity of 20 m/s.

If they skid for 8.6 seconds before stopping, how far did they skid? Hint: Are the aircraft moving at a constant velocity after the collision or do they experience an acceleration?(a) A 13.0 g wad of sticky clay is hurled horizontally at a 110 g wooden block initially at rest on a horizontal surface. The clay sticks to the block. After impact, the block slides 7.50 m before coming to rest. If the coefficient of friction between block and surface is 0.650, what was the speed of the clay (in m/s) immediately before impact? _____ m/s (b)What If? Could static friction prevent the block from moving after being struck by the wad of clay if the collision took place in a time interval Δt = 0.100 s? Explain your answer. Yes, a slightly larger coefficient of static friction could reasonably prevent the block from moving. No, the coefficient of static friction that would be required is unrealistically large.In the figure, determine the character of the collision.
