If a body weighs 12N on the surface of the earth, how much will it weigh on the surface of the moon where acceleration due to gravity is only one-sixth of that on earth's surface?
A) 12N
B) 2N
C) 10N
D) 6N
Answer: B) 2N
Explanation:
Weight is mass x g. Since mass is constant and g is only of that on the earth. The weight on the moon is only of that on the earth.
Due to an acceleration of 1 , the velocity of a body increases from 5 m/s to 10 m/s in a certain period. Find the displacement (in m) of the body in that period.
A body is initially moving with a velocity of 10 m/s. It undergoes an acceleration of 2 m/s2 for 5 seconds. Find the displacement (in m) of this body in these 5 seconds.
