Starting from rest, an elevator weighting 9000 N attains an upward velocity of 5 m/s in 4 sec. with uniform acceleration. Find the apparent weight of 600 N man standing inside the elevator during its ascent and calculate the tension in the supporting cable.

According to Newton’s second law of motion, force is defined as the product of mass and _____________

1. Weight

2. Moment of inertia

3. Acceleration

4. Velocity

Suppose a car is traveling eastward with some velocity. Can this car have a westward acceleration?

What will be the impact on the velocity of an object if it falls with constant acceleration?
