A 20-kg girl in an elevator is accelerated upward at a rate of 5 m/sec². What is the force due to the gravity acting on the girl? (use g-10 m/sec²) Ο.Α.Ο.Ν. B. 10 N C. 100 N D. 200 N E. 400 N
If you halve the distance between two masses of 70 kg each, their gravitational force changes by a factor of Mark for Review What's This?
A net force of 1 N is applied to move an object of mass 100 kg by 1 m. How much work is done? OA. IJ B. all alternatives wrong Mark for Review What's This? O C. 100 J O D. 10 J E. 1000 J Reset Selection
