Awheel with radius 0.0600 m rotates about a horizontal frictionless axle at its center. the moment of inertia of the wheel about the axle is 2.50 kg⋅m2. the wheel is initially at rest. then at t=0 a force f(t)=(4.50n/s)t is applied tangentially to the wheel and the wheel starts to rotate.

what is the magnitude of the force at the instant when the wheel has turned through 8.00 revolutions?

An ideal otto cycle has a compression ratio of 10.5, takes in air at 90 kpa and 40°c, and is repeated 2500 times per minute. using constant specific heats at room temperature, determine the thermal efficiency of this cycle and the rate of heat input if the cycle is to produce 90 kw of power.

Ball bearings are made by letting spherical drops of molten metal fall inside a talll tower-called a shot tower- and solidify as they fall. a-if a bearing needs 4.0 s to solidify enough for impact, how high must the tower be? b- what is the bearing's impact velocity?
