Hints

1.   Use Newton's second law to find the force

3.   Use Newton's second law to find the tension

7.   We know that the average force on the pellet is equal to its mass times its average acceleration. Perhaps consider using equation 2-11c to find the average acceleration

10. Use Newton's second law and sum forces in the y direction

19. Use 2 free body diagrams, one for the box and one for the weight. Note that if the weight of the weight is less than that of the box, there wil be no movement -

        what does this say about acceleration. Alternatively, if the weight weighs more than the box, there will be movement.

24. You can find the net force in each case using vector addition with components
