Physics

A child hits an ice cube with a mass of 10 grams on a table witha force of 10 N. The impact lasts 0.02 seconds. The ice cube fliesoff the table, which is 1 meter high and lands some distance away.Assume there is no friction between the ice cube and the table.

a. What is the velocity of the ice cube when it leaves thetable?

b. What is the final velocity of the ice cube just before ithits the floor?

c. What is the momentum of the ice cube just before it hits thefloor?

d. What distance will the ice cube land from the foot of thetable?

e. Suppose the ice cube had broken into two pieces just afterthe child hit the ice and moved away from each other while fallingto the floor. How would the total momentum of the two pieces justbefore they hit the floor compare to the momentum you found in part(c)?
