The radius of the earth's orbit around the sun (assumed to be circular) is 1.50 108 km, and the earth travels around this orbit in 365 days. (a) what is the magnitude of the orbital velocity of the earth in m/s? (b) what is the radial acceleration of the earth toward the sun in m/s2? (c) repeat parts (a) and (b) for the motion of the planet uranus (orbit radius = 2.87 109 km, orbital period = 84.02 years).

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
