Question

Unless otherwise stated, all objects are located near the Earth's surface, where = 9.80 .
Jane and John, with masses of 51kg and 66kg , respectively, stand on a frictionless surface 13m apart. John pulls on a rope that connects him to Jane, giving Jane an acceleration of 0.90 m/s^2 toward him.
a. What is the magnitude of Johns acceleration? (answer in m/s^2)
b. What is the direction of Johns acceleration?
c. If the pulling force is applied constantly, where will Jane and John meet? (answer in m, from Johns original position)

Explanation / Answer

this same force of 45.9N but opposite in direction to that of Jane's. So John with a mass of 66 Kg will have the following acceleration: Force John = Force Jane = 45.9 = 66*a John a John = 45.9/66 = .70 m/sec 2 opposite in direction to Janes acceleration. They in fact are pulled towards each other. With Jane acceleration of .90 m/sec 2 and John acceleration of .70 m/sec 2 and they are initially 13 m apart. the distance they each ...
