MECH 1B- FINAL QUIZ 2
1. Determine the impulse of the force for t = 2s
2. Determine the linear momentum of the 10kg block
3. If the coefficient of kinetic friction between the 150-lb crate and the ground is µk = 0.2, determine the
speed of the crate when t = 4 s. The crate starts from rest and is towed by the 100-lb force.
4. Determine the coefficient of restitution e between ball A and ball B. The velocities of A and B before
and after the collision are shown.
5. The 2.5-Mg van is traveling with a speed of 100 km/h when the brakes are applied and all four
wheels lock. If the speed decreases to 40 km/h in 5 s, determine the coefficient of kinetic friction
between the tires and the road
