Four forces act concurrently on a block on a horizontal surface as shown in the diagram
below.
As a result of these forces, the block
A) accelerate to the right
B) accelerate to the left
C) moves at constant speed to the right
D) moves at constant speed to the left

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
