Question A block of massm = 5.0 kg is pulled up a 0 = 23° incline as in the figure below with a force of magnitude F = 36 N. (a) Find the acceleration of the block if the incline is frictionless. (Give the magnitude of the acceleration.) |m/s² (b) Find the acceleration of the block if the coefficient of kinetic friction between the block and incline is 0.11. (Give the magnitude of the acceleration.) m/s²

A block of mass 11 kg lies on a horizontal plane. A force F that is inclined 42.3° with the horizontal is applied to the block (pulled the block) causing it to move 15 meters in 5 seconds. If the coefficient of friction between the block and the horizontal surface is 0.3, find the magnitude (N) of the force F. Round off only on the final answer expressed in 3 decimal places.

A 945.0kg car traveling rightward at 22.6 m/s slams on the brakes and skids to a stop (with locked wheels). If the coefficient of friction between tires and road is 0.9710, determine the force of friction. Use correct number of significant figures in answer Force =

An 5.2 kg wooden block is held against a wall with force (Fx) = 9.8 N.  The friction coefficient between the two surfaces (µ)=0.50.  Determine the acceleration of the block if a upward force of 36.0 N is applied.  Use positive for an upward acceleration and negative for a downward acceleration.

A student pushes a 20kg desk across the floor to the right with a force of 400 N. The coefficient of kinetic friction between the floor and the desk is equal to 0.21.  Calculate the acceleration of the desk.

For a short period of time, the frictional driving force acting on the wheels of the 2.3-Mg van is FD = (600+2) N, where t is in seconds.

The diagram below is a top-down view of two children pulling a 11.6-kg sled along the snow. The first child exerts a force of F1 = 10 N at an angle ?1 = 45° counterclockwise from the positive x direction. The second child exerts a force of F2 = 6 N at an angle ?2 = 30° clockwise from the positive x direction. (A) Find the magnitude (in N) and direction of the friction force acting on the sled if it moves with constant velocity. magnitude = ? direction (counterclockwise from the +x-axis) = ? (B) What is the coefficient of kinetic friction between the sled and the ground? (C) What is the magnitude of the acceleration (in m/s2) of the sled if F1 is doubled and F2 is halved in magnitude?
