7. A 100.0 kg man is standing on a scale in an elevator. The acceleration of the elevator is 3.0 m/s² [up]. Calculate his true weight and apparent weight during the ride.

A 60.8 kg person is standing inside an elevator. The elevator is moving upward at 3.49 m/s and is decreasing speed at a rate of 1.25 m/s^2. What is the force of gravity that is acting on the person?

An astronaut on the moon places a package on a scale and finds its weight to be 35 N. (a) What would the weight of the package be on the earth?                      N(b) What is the mass of the package on the moon?                      kg(c) What is the package's mass on earth?                       kg

Consider a person standing on a scale in an elavator. If the elevator accelerates upwards with an acceleration of 1.21 m/s^2 and the person has a mass of 102.9 kg, what would the scale read?

A person stands on a scale inside an elevator at rest. The scale reads 980 N. The elevator then accelerates upward momentarily at the rate of 4 m/s ^2 what does the scale read then?

The weight of an astronaut plus his space suit on the Moon is only 292 N. How much (in N) do they weigh on Earth? (The acceleration due to gravity on the Moon is 1.67 m/s2.)

1. A golf ball is hit from ground level with initial velocity given x(t)= 3 m/s(t) in a direction that is due east and at an angle theta above the horizontal. Neglecting air resistance, use Newton's second law to find the position as a function of time, using coordinates with x measured east and y north. Find the time for the golf ball to return to the ground and how far it travels in that time.
