Q1. Earth takes about 365 days to orbit once around the sun. Mercury, the innermost planet, takes less than a fourth of this time to complete one revolution. Assume some mysterious force causes Earth to experience an average angular acceleration of 6.05 × 10-13 rad/s2, so that after 12.0 days its angular orbital speed is the same as that of Mercury. Calculate this angular speed and the period of one orbit.
Q2. A 48.9 kg pole vaulter running at 13.0 m/s vaults over the bar. Assuming that the vaulter's horizontal component of velocity over the bar is 1.7 m/s and disregarding air resistance, how high was jump?

A Ferris wheel is a vertical, circular amusement ride with radius 6 m. Riders sit on seats that swivel to remain horizontal. The Ferris wheel rotates at the constant rate, going around once in 6.4 s. Consider a rider whose mass is 70 kg.
A wheel 45.0 cm in diameter accelerates uniformly from 206rpm to 340 rpm in 7.0 s. How far will a point on edge of the wheel have travelled in this time.
