A wheel, starting from rest, rotates with a constant angular acceleration of 1.20 rad/s2. During a certain 2.00 s interval, it turns through 4.60 rad. (a) How long had the wheel been turning before the start of the 2.00 s interval? (b) What was the angular velocity of the wheel at the start of the 2.00 s interval?

Aparticle initially moving east with a speed of 20.0 m/s, experiences an acceleration of 3.95 m/s, north for a time of 8.00 s. what was the speed of the particle after this acceleration, in units of m/s? give the answer as a positive number.

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.
