–/6.25 points sercp11 4.5.p.037.my notes question part points submissions used (a) an elevator of mass m moving upward has two forces acting on it: the upward force of tension in the cable and the downward force due to gravity. when the elevator is accelerating upward, which is greater, t or w?

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

It equals just about 6,300 km per hour each day an week
