Answer:
145.43 N
Explanation:
Weight is given by (mg)
where m = mass of the body
g = acceleration due to gravity
mass is constant everywhere and is equal to 77.1 kg, both on the earth and on the moon.
But the acceleration due to gravity exerted by the moon near the moon's surface is 16.6% that of Earth,
g(moon) = 0.166 g(earth) = 0.166 × 9.8 = 1.6268 m/s²
Weight on the moon = mg(moon) = (77.1×1.6268) = 125.43 N
Answer:
Less
Explanation:
because static friction is more than rolling friction
2*3.5 = 7m/s
You multiply the acceleration per the time (they both are in seconds, otherwise, you should set them in the same units).
