Calculate the magnitude of his cart’s acceleration. A cleaner pushes a 4.50-kg laundry cart in such a way that the net external force on it is 60.0 N.If the sprinter from the previous problem accelerates at that rate for 20.00 m and then maintains that velocity for the remainder of a 100.00-m dash, what will her time be for the race?.Andrea, a 63.0-kg sprinter, starts a race with an acceleration of 4.200 m/s 2.(b) Find the magnitude of the resultant (net) force on the tree and the angle it makes with David’s rope. (a) Find the component form of the net force.

David pulls with a force of 400.0 N and Stephanie pulls with a force of 300.0 N. Two teenagers are pulling on ropes attached to a tree.(b) Find the magnitude and direction of this net force. (a) Find the net force on the telephone pole in component form.
