An astronaut takes a 6.5 kg bowling ball to the moon, which has a gravitational acceleration of 1.6 m/s 2 . What is the weight of the ball while it is on the moon? A. 4.06 N B. 4.9 N C. 8.1 N D. 10.4 N

D.  10.4 N

Explanation:

Hi there,

To get started, recall the formula for magnitude of weight:

 where m is mass in kilograms, and ag is acceleration due to gravity on that astronomical body, which is the moon in this case.

Both the mass and acceleration are in SI units, so we can go ahead and plug right in!

The SI unit of force is Newton (N).

Thus, the weight of the ball on the moon is D. 10.4 N.

thanks,

not too sure thinking all accelerations are pointed down

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
