Question 1: Using Newton's Universal Law of Gravitation, for a 65.0-kg object, which what is the gravitational force on.
c.) the surface of the earth (m=5.98x10^24 kg, radius = 6,370 km)?
d.) The surface of the titan (m=1.35 x 10^23 kg, radius= 2,580 km)?
e.) the surface of mars (m=6.39 x 10^23 kg, radius = 3,390 km)?
Question 2: a.) Draw a free-body diagram of forces on a box slowing down as it slides rightward on the floor.
b.) if the 7.00 -kg box has a coefficient of kinetic friction of 0.250, what is the magnitude of the friction force?
c.) how long would it take to come to rest if its initial speed was 10.00 m/s?
