A cylinder having a mass of 40 kg with a radius of 0.5 m is pushed to the right without rotation and with acceleration 2 m/sec2. Determine the magnitude and location of the horizontal force P if the coefficient of friction is 0.30.

What will be the force of static friction on a crate lying on a horizontal ramp?

If the net force on a cart is tripled then what will be the net acceleration?

1. There will be no change in acceleration

2. The net acceleration will be tripled 

3. The net acceleration will be double

4. The next acceleration will be one-third

(a) Determine the average velcoity of the particle at t=6 seconds.

(b) Determine the average speed of the particle at t=6 seconds.

(c) Determine the average acceleration of the particle at t=6 seconds.
