You have a light spring which obeys Hooke's law. This spring stretches 3.04 cm vertically when a 2.90 kg object is suspended from it. Determine the following. (a) the force constant of the spring (in N/m) N/m (b) the distance (in cm) the spring stretches if you replace the 2.90 kg object with a 1.45 kg object cm (c) the amount of work (in J) an external agent must do to stretch the spring 8.10 cm from its unstretched position J
NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. When the rope is at an angle of a = 30°, the 1-kg sphere A has a speed vo=0.6 m/s. The coefficient of restitution between A and the 2-kg wedge B is 0.8 and the length of rope /= 0.9 m. The spring constant has a value of 1550 N/m and 8 = 20⁰. NO k www Determine the velocities of A and B immediately after the impact. The velocity of A immediately after the impact is [ The velocity of B immediately after the impact is Chea m/s .. m/s.
Khufra works at a spring factory and he was assigned to test a certain spring, whose constant is 45 N/m, attached to a 15-kg block in an incline (0 = 49°). With the spring initially at equilibrium position, the block was pushed 0.5 meters up the incline by a 32-N external force applied parallel to the path. If the coefficient of kinetic friction is 0.3, determine the normal force (in Newtons). Use g = 9.81 m/s². CH 8
A factory worker drops a 10 kg steel block from rest (m=10). The block then falls 30 cm onto a vertical spring standing on the floor. The spring constant of the spring is 400 N/m (k=400). The block makes contact with the spring, it then continues to move downward, compressing the spring until it comes to rest. (The spring then decompresses, firing the block upward.) Determine the distance that the spring was compressed by the block.

During spring semester at MIT, residents of the parallel buildings of the East Campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. A balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. Assume that the stretching of the hose obeys Hooke's law with a spring constant of 130 N/m. If the hose is stretched by 5.30 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length?
