A 1200-kg car, initially moving at 20 m/s, comes to a stop at a red light over a time of 3 s from the moment the driver hit the brakes.

For projectile motion on level ground assuming negligible air resistance (the initial angle being neither 0o nor 90o) : Can the speed ever be the same as the initial speed at a time other than at t = 0? a. No b.

8. A gas is contained in a horizontal piston-cylinder apparatus at a pressure of 350 kPa and a volume of 0.02 m3. Determine the work done by the piston on the gas if the cylinder volume is increased to 0.15 m3 through heating.
