When a projectile is at its maximum height, the direction of its velocity and acceleration are

The angular displacement theta radians of a fly wheel varies with time t seconds and follow the equation theta = 9t^(2) - 2t^(3) . Determine the angular velocity and acceleration of the fly wheel when time t =1 seconds and (ii) The time when the angular acceleration is zero.

A bucket is being lowered down into a well through a rope passing over a fixed pulley of radius 10 cm. Assume that the rope does not slip on the pulley. Find the angular velocity and angular acceleration of the pulley at an instant when the bucket is going down at at speed of 20 cm/s and has an acceleration of 4.0 m/s^2 .

What is the angle between velocity and acceleration at the highest point of a projectile motion?

Derive the equation for Velocity - displacement relation.

Assertion : In simple harmonic motion the velocity is maximum when the acceleration is minimum. Reason : In simple harmonic motion the phase difference between velocity and acceleration is (pi)/(2) Select the correct option form the following.

A particle is in linear simple harmonic motion between two points, A and B, 10 cm apart. Take the direction from A to B as the positive direction and give the signs of velocity, acceleration and force on the particle when it is at the end A.
