What is a motion diagram?

I had a problem solving for part b of this question: objects with masses of 110 kg and a 410 kg are separated by 0.380 m. (a) find the net gravitational force exerted by these objects on a 30.0-kg object placed midway between them.

At 3:00 a car passes mile marker 74 as it cruises along the highway. The car then passes mile marker 124 as the clock reads 3:45. How fast was the car moving?

A solid ball and a hollow ball, each with a mass of 1.00 kg and radius of 0.100 m start from rest and roll down a ramp of length 3.00 m at an incline of 35.0 degrees. AN ice cube of the same mass slides without friction down the same ramp.

A helium balloon ride lifts up passengers in a basket. Assume the density of air is 1.28 kg/m3 and the density of helium in the balloon is 0.18 kg/m3. The radius of the balloon (when filled) is R = 4.5 m.
