3 boxes are connected by strings and are being pulled along by a rope. The boxes have masses of 1kg, 2kg and 3kg. Consider Friction to be negligible. If the boxes are pulled along at an acceleration of 4m/s^2, What is the tension in the rope pulling them?

1. a net force of 100 newton’s is applied to a wagon for 5 seconds. this causes the wagon to undergo a change in momentum of

The position of a crate sliding down a ramp is given by x=(0.05t^3) m, y=(1.7t^2) m, z=(6−0.85t^5/2) m, where t is in seconds. (a) determine the magnitude of the crate's velocity when t = 2 s. (b) determine the magnitude of the crate's acceleration when t = 2 s.
