Answer:
the answer is 0.625.
And this is because force is defined by the formula mass× acceleration and in this question acceleration is not given but we know the formula for acceleration is velocity over time.
So we can get acceleration it becomes 5/6 which is 0.83 this is the acceleration and we have gotten the acceleration the formula for force is mass times acceleration that is 0.75 x 0.83 and that is 0.625
