A bullet of mass 5.00g is fired horizontally into a wooden block of mass 1.30 kg resting on a horizontal surface. The coefficient of kinetic friction between block and surface is 0.210. The bullet remains embedded in the block, which is observed to slide a distance 0.200m along the surface before stopping.
What was the initial speed of the bullet?
A trunk with a weight of 230 N rests on the floor. The coefficient of static friction between the trunk and the floor is 0.32, what would be the acceleration of the trunk
A 2.8 kg block slides along a frictionless horizontal with a speed of 5.5 m/s. After sliding a distance of 8m, the block makes a smooth transition to a frictionless ramp inclined at an angle of 43 degrees to the horizontal. The acceleration of gravit..
