As part of a physics experiment, you stand on a bathroom scale in an elevator. even though you actual weight 704 N, the scale reads 894 N. The elevator is accelerating upward, your apparent weight in the elevator is 894 N, the elevator's acceleration is 2.65 m/s^2. What is the downward acceleration of the elevator that is required so you feel weightless? If the elevator is moving up or down with a constant speed, you apparent weight is?
"A student pulls a box of books on a smooth horizontal floor with a force of 100 N in a direction of 37° above the horizontal. If the mass of the box and the books is 40.0 kg, what is the acceleration of the box?"
1.5 m/s2
1.9 m/s2
2.0 m/s2
3.3 m/s2
The weight of a mass on Mercury, where the acceleration due to gravity is 3.61 m/s2, is 1235 N. What would be the weight of the same mass on the Moon, where the acceleration due to gravity is 1.60 m/s2?
