A large toy car is pushed horizontally by a spring, and the spring has a spring constant of 135 N/m. What is the mass of the toy car if compressing the spring 0.055 m (before the toy starts moving) causes it to reach a speed of 0.75 m/s? (Note - the height of the toy does not change.) What equation will be best for calculating this value? Your answer: O mgh, = O mgh, =mv? %3D 0 글씨로=mghy

You attach a 2.10 kg weight to a horizontal spring that is fixed at one end. You pull the weight until the spring is stretched by 0.300 m and release it from rest. Assume the weight slides on a horizontal surface with negligible friction. The weight reaches a speed of zero again 0.100 s after release (for the first time after release). What is the maximum speed of the weight (in m/s)? m/s Need Help? Read It Submit Answer
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 120 N/m. If the hose is stretched by 2.30 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? Number i Units
