Solve the all parts of following question:
Question: A block of ice with a mass of 2.50kg is moving on a frictionless, horizontal surface. At t=0, the block is moving to the right with a velocity of magnitude 6.00m/s.
Part A: Calculate the magnitude of the velocity of the block after the following force has been applied for 6.00s: a force of 6.00N directed to the right.
Part B: Calculate the magnitude of the velocity of the block after the following force has been applied for 6.00s: a force of 7.50N directed to the left.
Please show all work and steps I am really trying to learn this for my test.
