A block is on a frictionless horizontal table, on earth. This block accelerates at 3.6 m/s2 when a 90 N horizontal force is applied to it. The block and table are then set up on the moon where the acceleration due to gravity is 1.62 m/s2

A horizontal force of 45 N is applied to the block when it is on the moon. What acceleration does this force impart to the block? A) 1.8 m/s2
B) 1.6 m/s2
C) 2.0 m/s2
D) 2.2 m/s2
E) 2.3 m/s2

A uniform, horizontal beam of length 6.0 m and weight 140 N is attached at one end to a wall by a pin connection (so that it may rotate). A cable attached to the wall above the pin supports the opposite end. The cable makes an angle of 60° with the horizontal. What is the tension in the cable needed to maintain the beam in equilibrium?

a. 81 N c. 70 N b. 69 N d. 140 N
