- Uk TTTTTTTTTTTTTTTTTTTTTTI A block of mass m = 16.8 kg is sliding on a surface with initial velocity v = 23.2 m/s. The block has a coefficient of kinetic friction ulk = 0.426 with respect to the surface and is being pushed by a force of magnitude F = 54.3 N in the direction of its motion. Due to kinetic friction, the block is slowing down. How long will it take for the block to come to a stop? Pick the correct answer O 2.02 s O 22.0 s 03.13 s O 0.947 s O 24.5 s Hk M ĚL TTTTTTTTTTTTTTTTTTTTTTI You are pushing a block with force Fi = 124 N at a downward angle 0 = 40° from the horizontal and your friend is pulling the same block with force F2 = 162 N horizontally in the same direction. The block has mass m = 53.0 kg and is moving with acceleration a in the direction of the exerted force F2. If the coefficient of kinetic friction fk = .250 between the block and the floor, what is the magnitude of acceleration à that the block experiences? Pick the correct answer O 2.40 m/s2 O 1.66 m/s2 O2.02 m/s2 O 6.47 m/s2 O 107 m/s2
