1.	For how many seconds would a force of 8N have to act on a 2kg mass in order to change its velocity from 2m/s to 7m/s.
Answer» hey dude ....here's your answerExplanation:Given :-Force = 8N Mass = 2 kgInitial velocity (u)= 2m/sFinal velocity (v) = 7m/sWe know, thatForce = mass × acceleration 8 = 2 × v- u / t8/2 = 7- 2 / T4 t = 5t = 5/ 4 t = 1.25 seconds
