Answer:
weight!!!! Free fall is the motion of a body where its weight is the only force acting on an object.
Answer:This also means that Mercury's surface gravity is 3.7 m/s2, which is the equivalent of 38% of Earth's gravity (0.38 g). This means that if you weighed 100 kg (220 lbs) on Earth, you would weigh 38 kg (84 lbs) on Mercury.
Explanation:
Answer:
d = 13.7 m
Explanation:
When block is moving upwards along the inclined plane
then the block is decelerated due to gravity as well as due to friction and speed of the block by which it is projected upwards is given

deceleration caused to the block due to net force opposite to the motion is given as



since block is sliding on the inclined plane
so here we can say that the coefficient of the friction must be kinetic friction here


now for finding the distance upto which it will stop is given as



Answer:
