Question

Physics: Include all significant figures please.

1. A bowling ball (mass = 4.3 kg, radius = 0.11 m) and a billiard ball (mass = 0.39 kg, radius = 0.028 m) may each be treated as uniform spheres. What is the magnitude of the maximum gravitational force that each can exert on the other?

2. In tests on earth a lunar surface exploration vehicle (mass = 5.97 × 103 kg) achieves a forward acceleration of 0.205 m/s2. To achieve this same acceleration on the moon, the vehicle's engines must produce a drive force of 1.57 × 103 N. What is the magnitude of the frictional force that acts on the vehicle on the moon?

3. The drawing shows three particles far away from any other objects and located on a straight line. The masses of these particles are mA = 312 kg, mB = 581 kg, and mC = 160 kg. Take the positive direction to be to the right. Find the net gravitational force, including sign, acting on (a) particle A, (b) particle B, and (c) particle C.

Explanation / Answer

Multiple questions According to the chegg guidelines I am allowed to answer only 1 question at a time.

Solution 1) we need to find the maximum gravitational force that each can exert on the other

for that we have a formula

F=G*m1*m2/r^2 = 6.67*10^-11 m^3 * 4.3 kg * 0.39 kg / (0.138 m ) ^2

F = 5.87355 * 10 ^ -9 Newton or 5.87355 nano Newton =============ANSWER)
