From what height (in m) was the ball dropped, if the magnitude of the ball's momentum is 0.780 kg m/s just before it lands on the ground? mQuestion 5bi - Momentum and Impulse A small car, with a mass of 725 kg, is moving at 26 ms towards the East. A second car, with a mass of 2175 kg, has the same momentum. The driver of the first smaller car (mass 725 kg) suddenly applies their brakes hard for 2.0s. As a result, an average force of 5.0 kN is exerted to slow the car down. Calculate the change in magnitude and direction of the impulse on the car.
- A0.014-kg bullet is fired intoa stationary block of wood of mass of 4.51 kg. The relative speed of the bullet with respect to the wood is zero after collision (The bullet becomes embedded in the block of wood).

Show why or why not, based on your data.2. Conservation of Linear Momentum See Figure 2. Block 1 of mass m₁ slides from rest along a frictionless ramp from an unknown heighth and then collides with stationary block 2, which has mass m₂ = 3m₁ . The collision is an elastic one. After the collision, block 2 slides into a friction-filled region where the coefficient of kinetic friction is 0.5 and comes to a stop through a distance d = 10 m in that region. (a) What is the height h? (ANSWER: h = 20 m) (b) What is the velocity of block 1 just after the collision?
