In tests on earth a lunar surface exploration vehicle (mass = 5.90 103 kg) achieves a forward acceleration of 0.215 m/s2. To achieve this same acceleration on the moon, the vehicle's engines must produce a drive force of 1.64 103 N. What is the magnitude of the frictional force that acts on the vehicle on the moon?

• Physics -

Fap - Ff =ma.
1640 - Ff = 5900*0.215 = 1269 N.
-Ff = 1269 - 1640 = -371
Ff = 371 N. = Force of friction.
