Xavier is driving at 12 m/s and decreases his velocity by 4 m/s^2. What is his stopping distance?

Suppose that 27 j of work is needed to stretch a spring from its natural length of 6 m to a length of 9 m. (a) how much work is needed to stretch the spring from 12 m to 14 m? j (b) how far beyond its natural length will a force of 78 n keep the spring stretched?

How can you measure the amplitude of a longitudinal wave?
