A ball with m=0.1 kg swings from point 1 to point 3. Assuming that point 3 is 2 m above the lowest point 2. If the tension force on the string at point 2 is T=10 N, What his the length of the string? Assume the mass of string is ignorable.
A spring is used to stop a 60 kg package that is sliding on a horizontal surface. The spring has a constant
K = 20,000 N/m and is held by cables so that it is initially compressed 0.12 m. The package has a velocity
of 2.5 m/s in the position shown, and the maximum additional deflection is 0.04 m. Determine:
(a) the coefficient of friction between package and the surface,
(b) the velocity of the package as it passes again through the position shown.

A 3 kg block is placed on frictionless horizontal surface next to a spring, sticking out horizontally from the wall; a Force applied to the block at 30° below horizontal is gradually increased, until –300 N (diagonal) has compressed the spring (–)0.20 m (horizontal). When the Force is removed suddenly, the block slides along frictionless floor and crosses 0.30 m long sandpaper (friction coefficient 0.66), before reaching a frictionless ramp. What is the block’s speed after crossing the sandpaper?
