One way to store energy is in the rotational motion of a flywheel, and some have proposed using such technology to power automobiles. One unit is based on a 5.5-kg flywheel in the shape of a hoop of radius 7.0×10−2 m that spins as fast as 60000 rpm. If the vehicle requires an average torque of 142 Nm under normal driving conditions, for how much time can it operate with the energy stored in the flywheel?

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
