A 4 kg object, moving on a flat horizontal surface in a straight line, experiences a net force, F = -2t. If the initial velocity is +4 m/s, at what time will the object come to rest?

Awheel rotates without friction about a stationary horizontal axis at the center of the wheel. a constant tangential force equal to 82.0 n is applied to the rim of the wheel. the wheel has radius 0.150 m . starting from rest, the wheel has an angular speed of 12.8 rev/s after 3.88 s. what is the moment of inertia of the wheel?
