11. A sled at Canada Olympic Park in Calgary has a mass of 25.0 kg. A rider with a mass of 78.0 kg begins the run by pushing the sled to a speed of 1.20 m/s. By the time the sled gets to the first turn in the track, it has gained 2.25 x 10° J of kinetic energy. At that time, what is the speed of the combined mass?

A 5.00-kg block is set into motion up an inclined plane with an initial speed of i = 8.00 m/s (Fig. P8.23). The block comes to rest after traveling d = 3.00 m along the plane, which is inclined at an angle of = 30.0 to the horizontal.

Two blocks of masses m and 3m are placed on a frictionless, horizontal surface. A light spring is attached to the more massive block, and the blocks are pushed together with the spring between them (Fig. P8.7).

Ezra (m = 25.0 kg) has a tire swing and wants to swing as high as possible. He thinks that his best option is to run as fast as he can and jump onto the tire at full speed. The tire has a mass of 10.0 kg and hangs 3.75 m straight down from a tree branch. Ezra stands back 10.0 m and accelerates to a speed of 3.50 m /s before jumping onto the tire swing. a. How fast are Ezra and the tire moving immediately after he jumps onto the swing? b. How high does the tire travel above its initial height?
