Answer 2

ime, t = 4.57 seconds

Explanation:

Given that,

Net force acting on the object, F = 7 N

Mass of the object, m = 400 g = 0.4 kg

Initial velocity of the object, u = 0

Final velocity of the object, v = 80 m/s

Let t is the time taken to reach its final velocity. The net force acting on the object is given by :

F = m a

F=m*v-u/t
