Four identical wooden blocks are slid with same initial velocities on four different horizontal surfaces - sand, concrete, clay and ice. On which of these surfaces, will the distance travelled be maximum?
Ice
When a body is slid along a horizontal surface, frictional force opposes its motion. This means that the body will travel to the maximum distance on the surface having least friction. Among the given surfaces, ice has the least friction and the ball will travel the farthest on ice.
