Question

A record on a record-player rotating at 9.0 rad/s slows to a stop in 6 s. If the acceleration is constant, the angle through which the turntable rotates in the 6 s is O 0.80 rad O 0.40 rad O 40 rad O 80 rad O 27 rad

Answer 1

A change in velocity that does not fluctuate over a specific period of time is referred to as constant acceleration.

A car's average acceleration remains constant at 20 mph per minute even if it increases its speed by 20 mph during the course of one minute and then by another 20 mph the next. The experiment demonstrates that acceleration is frequently variable. In truth, acceleration can alter and does so at a certain rate. Velocity is the measure of how quickly a distance changes (or, more precisely, "displacement"). Acceleration is the measure of a change in velocity. An object's acceleration is the rate at which its velocity changes in relation to time. A constant velocity guarantees that an object's rate of change in velocity over time is zero, and as a result, the object's acceleration is zero.
