Starting from rest, a car accelerated for 4.0 seconds with an acceleration a. It continued for an additional 12.0 seconds with an acceleration a/2, reaching a final speed of 20 m/s. How far did the car travel in the total time of 16 seconds?
A body moving with simple harmonic motion has an amplitude of 10cm and a frequency of 100HZ, find (a) the period of oscillation (b) the acceleration at the maximum displacement (c) the velocity at the centre of motion.
If a body moving with simple harmonic motion has an angular velocity of 50 radians per second and an amplitude of 10cm, calculate its linear velocity.
