A model rocket (m = 1.0 kg) is launched from the ground, starting from rest, and accelerates vertically due to an upward thrust of F= 25 N being produced by the rocket's engine. The rocket accelerates vertically for a time of t = 10 s at which point the rocket's engine runs out of fuel. Assume that the rocket's engine runs out of fuel instantaneously and stops operating and that the fuel contributes a negligible amount to the rocket's mass. That is, you may assume that the rocket's mass remains m = 1.0 kg throughout the entire problem. To what height above the point at which the rocket runs out of fuel does the rocket reach? (g = 9.8 m/s) O A) 1178 m O B) 1136 m O C) 1098 m O D) 1267 m O E) 1231 m

A student of mass 63 kg falls freely from rest and strikes the ground. During the collision with the ground, he comes to rest at a time of 0.04 seconds. The average force exerted on him by the ground is 18,000 N, where the upward direction is taken to be a positive direction. From what height did the student fall? Assume that the only force acting on him during the collision is only due to the ground

A toy rocket operates by having a spring-loaded tube which ejects a small model rocket when released. The spring inside has a spring constant k = 625N/m, the rocket has a mass of 0.100 kg, and the maximum compression of the spring is 0.18 m. Consider the system of the rocket, spring, and the earth. Consider the interval of time between t1, when the rocket is released from the point of maximum spring compression, and t2, the moment when the spring is fully released and the rocket leaves the launcher. List below the types of energy that are changing during this interval and whether the changes are positive or negative. Please explain how you know.

A 66.0-kg athlete leaps straight up into the air from a trampoline with an initial speed of 7.5 m/s. The goal of this problem is to find the maximum height she attains and her speed at half maximum height. (a) What are the interacting objects and how do they interact? This answer has not been graded yet. (b) Select the height at which the athlete's speed is 7.5 m/s as y = 0. What is her kinetic energy at this point?
