3. An 85-kg man stands on a spring scale in an elevator which starts from rest. The tension T in the hoisting cable is given by the function 35.30x²+ 8000 Newtons where t is in seconds. Find the reading R of the scale in newtons at t=5.60s and the velocity v of the elevator at the end of the 5.60seconds. The total mass of the elevator, man, and scale is 760 kg.

A person doing a chin-up weighs 700 N, exclusive of the arms. During the first 25.0 cm of the lift, each arm exerts an upward force of 355 N on the torso. If the upward movement starts from rest, what is the persons velocity at that point?
Calculate the maximum acceleration of a car that is heading up a 4.00slope (one that makes an angle of 4.00with the horizontal) under the following road conditions.

While moving into your new place, you have to push a 25-kg box across the foor. You push on it with someforce at angle of 27◦ below your shoulder, as shown in the fgure. Assuming the coefcient of static frictionbetween the box and foor is 0.60, with what force do you need to push to just get the box moving? (Hint: itis safe to assume that the acceleration of the box is still zero at the instant it starts moving.)
