A model rocket engine has an average thrust of 5.26 N. It has an initial mass of 25.5 g, which includes fuel mass of 12.7 g. The duration of its burn is 1.90 s. (a) What is the average exhaust speed of the engine? (b) This engine is placed in a rocket body of mass 53.5 g. What is the final velocity of the rocket if it were to be fired from rest in outer space by an astronaut on a spacewalk? Assume the fuel burns at a constant rate.
Two figure skaters are coasting in the same direction, with the leading skater moving at 5.5 m/s and the trailing skating moving at 6.2 m/s. When the trailing skater catches up with the leading skater, he picks her up without applying any horizontal forces on his skates. If the trailing skater is 50 heavier than the 50-kg leading skater, what is their speed after he picks her up?
NASAs Saturn V rockets that launched astronauts to the moon were powered by the strongest rocket engine ever developed, providing 6.77 106 N of thrust while burning fuel at a rate of 2.63 103 kg/s. Calculate the engines exhaust speed.

Two objects of masses m1 = 0.56 kg m2 = 0.88 kg are placed on a horizontal frictionless surface and a compressed spring of force constant k = 280 N/m is placed between them as in Figure P6.28a. Neglect the mass of the spring. The spring is not attached to either object and is compressed a distance of 9.8 cm. If the objects are released from rest, find the final velocity of each object as shown in Figure P6.28b. Figure P6.28

A bullet is accelerated down the barrel of a gun by hot gases produced in the combustion of gun powder. What is the average force exerted on a 0.0300 kg bullet to accelerate it to a speed of 600 m/s in a time of 2.00 ms? Group of answer choices 36.0 mN 9.00 kN 100 nN 40.0 N
A 0.663-kg ball, initially moving with a speed of 3.09 m/s, bounces off a wall and then moves with a speed magnitude half of its original directed in the opposite direction. If the ball is in contact with the wall for 5.4 ms, what is the magnitude of the average force that the wall exerts on the ball? Express your answer in two decimal places, in Newtons.
After falling from rest from a height of 30-m, a 0.50-kg ball rebounds upward, reaching a maximum height of 20-m. If the contact between the ball and the ground lasted 20 milliseconds, what average force was exerted on the ball by the ground? (Hint: consider the change in velocity that has occurred between the interval just before and just after hitting the ground). Answer: 1.1 x 10^3 N
