Thor, Norse God of Thunder, is rumored to be the strongest of the Asgardians. Suppose in his battle against Thanos, Thor lifts a mass of 7.9 gigagrams with an upward velocity of 5.7 cm/s to a maximum height. The mass is initially at rest and reaches its upward speed because of a net force of 36.7 kilonewtons exerted upward. For how long (in seconds) is this force applied?

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
