Question1

A 67 human sprinters can accelerate from rest to 11 in 3.0. Throughout the similar interval, a 32 greyhound can accelerate from rest to 22. Compute

(a) Change in kinetic energy and

(b) Average power output for each.

Question2

At t=0 a grinding wheel has an angular velocity of 23.0 rad/s. It has a constant angular acceleration of 31.0 rad/s^2 until a circuit breaker trips at time t = 2.50s. From then on, it turns throughout an angle 437 radians as it coasts to a stop at constant angular acceleration. Through what total angle did the wheel turn between t=0 and time it stopped?
