A woman has a mass of 55.0 kg.a. What is her weight on earth?b. What are her mass and her weight on the moon, where g = 1.62 m/s2?
A 1,000.0-kg particle is placed at the origin. A 5,000.00-kg particle is placed on the x-axis at the 1.0 mm mark. A third particle with mass of 2,000.0 kg is placed on the x-axis at the 2.0 mm mark.
Determine the magnitude of the net gravitational force experienced by the third particle.
O a. 19,600.000 N
O b. 78,400.000 N
O . 633.650 N
O d. 700.350 N
A couple of astronauts agree to rendezvous in space after hours. Their plan is to let gravity
bring them together. One of them has a mass of 65.0 kg and the other a mass of 72.0 kg
and they start from rest 20.0 m apart.
a. Draw a free-body diagram of each astronaut, and use it to find his or her initial
acceleration. As a rough approximation, we can model the astronauts as uniform
spheres.
b. If the astronauts' acceleration remained constant, how many days would they have
to wait before reaching each other? Careful! They both have acceleration toward
each other!
c. Would their acceleration, in fact, remain constant? If not, would it increase or
decrease? Why?
