Q. A simple pendulum has length of 2m and mass of 0.5 kg.It is hanging from the room of a car that is travelling at 5 m/s and banking a corner of radius 15m
1. Compute the time period of oscillation for the pendulum.
2. If the car is now at rest and the pendulum undergoes S.H.M. would its time be shorter of longer than that calculated in (b) explain your answer.

A 10 kg runaway grocery cart runs into a spring with spring constant 240N/m and compresses it by 65cm. What was the speed of the cart just before it hit the spring.
A horse canters away from its trainer in a straight line, moving 130 m away in 10.0 s. It then turns abruptly and gallops halfway back in 5.3 s. find its average velocity for the entire trip, using "away from the trainer" as the positive direction..
The leg and cast weigh 220 N, with the center of mass as indicated by the blue arrow in the diagram. The counterbalance w1 weighs 135 N. find the weight w2 and the angle α needed so that no force is exerted on the hip joint by the leg plus cast.
A 258-kg log is pulled up a ramp by means of a rope that is parallel to the surface of the ramp. The ramp is inclined at 30.0° with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is 0.980, and the log has ..
