A rocket has initial mass of 25x10 kg of which 80 percent is the Q) fuel and the rest is payload. If burns fuel at a rate of 200 kg/s and exhaust its gas at a relative speed of 1.8 km/s: a) Find the thrust of the rocket. b) Find the time until burnout, and c) After firing for 50 seconds i- find the mass of the rocket, and ii- find its speed assuming it moves upward near the surface of the earth ( neglect the earth's rotation).

Find the impulse and the average force exerted on the block by the fist during the collision.
A billiard ball, labeled 1, moving horizontally strikes another billiard ball, labeled 2, at rest. Before impact, ball 1 was moving at a speed of 3.00 m/s, and after impact it is moving at 0.50 m/s at 50 from the original direction. If the two balls have equal masses of 300 g, what is the velocity of the ball 2 after the impact?
