Q. A 240-g block is pressed against a spring of force constant 1.20 kN/m until the block compresses the spring 10.0 cm. The spring rests at the bottom of a ramp inclined at 60.0° to the horizontal. Using energy considerations, determine how far up the incline the block moves from its initial position before it stops under the following conditions.

Q. A 79 kg pole-vaulter falls from rest from a height of 4.6 m onto a foam-rubber pad. The pole-vaulter comes to rest 0.30 s after landing on the pad.Calculate the athlete's velocity just before reaching the pad.
