A car is initially traveling at a speed of 90 km/h, suddenly brakes so that the speed becomes 36 km / h in an interval of 6 s. If style that stops the car at 3200 N, what is the mass of the car?

A high-speed photograph of a club hitting a golf ball is shownin Figure 6.3. The club was in contact with a ball, initially atrest, for about 0.002 0 s. If the ball has a mass of 55 g andleaves the head of the club with a speed of 2.0 x 102 ft/s, findthe average force exerted on the ball by the club.

During a practice dive, a 45-kgkg diver jumped to a maximum height of 4.4 mm above the water before coming down and entering the water. She came to rest 0.40 ss after hitting the water. Determine the average force that the water exerted on her while stopping her.

A 15-g bullet traveling 399 m/s in a vertical direction buries itself in a 3 kg block of wood at rest directly above it.  As a result, the bullet/block combination moves vertically upward together. Determine the maximum height reached by the bullet/block combination.

If a rocket engine ejects gases at a rate of 29 kg/s, how fast must the gaseous exhaust be moving if the thrust produced is sufficient to allow a 2.7 x 105 kg rocket to rise slowly from the earth when aimed straight up? Express your answer in km/s.

I would appreciate some hwlp with this question. Thanks!   A model rocket consisting of a 61.0-g chassis and a 30.5-g engine is taken on an interstellar mission and fired in outer space. The engine produces 5.00 N of thrust while expending 13.0 g of fuel at a constant rate during a 2.04-s burn. (Assume the mass of the engine includes the mass of the fuel.) (a) What is the average exhaust speed of this rocket's engine?   (b) If the rocket starts from rest, what is its final velocity? (Assume the thrust to be in the positive direction. Indicate the direction with the sign of your answer.)
