1. Two forces act on a parachutist during a drop. One force is the weight W(500N) of the parachutist. The other force is the upwards pull P(400N) from the parachute harness on the parachutist. The parachutist has a mass of 50 kg.
a. What is the size of the unbalanced force acting on the parachutist?
b. What is the acceleration of the parachutist?
1. A boat engine produces a force of 10000 N and the friction and water resistance total 3500 N. If the mass of the boat is 2000 kg, what will be its acceleration?
