A box moves to the right along a rough, wooden surface. In which direction does the box experience a frictional force?

to the right, in the same direction as the object’s motion

to the left, in the opposite direction of the object’s motion

in neither direction, because the surface would not result in friction on the box

to the left and right, because it’s moving in the horizontal direction

The man fires an 80 g arrow so that it is moving at 80 m/s when it hits and embeds in a 8.0 kg block resting on ice. how far will the block slide on the ice before stopping? a 7.1 n friction force opposes its motion.

The force needed to overcome static friction is usually less than that needed to overcome kinetic friction.true or false?

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.
