You are riding a bicycle. If you apply a forward force of 125 N, and you and the bicycle have a combined mass of 82 kg, what will be the forward
acceleration of the bicycle? (Assume there is no friction.)

Auniform bridge, 20 m long and weighing 40000 n is supported by two pillars located 3.0 m from each end. if a 19600 n car is parked 8.0 m from one end of the bridge, how much force does each pillar exert?

An experiment was performed on a 2-kg block. forces of 5, 10 and 15 newtons respectively were applied to the block for 5 seconds. describe the difference in acceleration between the three trials. a) the final accelerations will all be the same. b) the final acceleration will triple between the first and third trial. c) the final acceleration will be cut by 1/3 from the first to third trial. d) the final acceleration will increase nine time between the first and third trial.
