what constant force p is required to bring a 50kg body which starts from rest to a speed of 10m/s in 7m neglect friction

use v² -u² =2*a*s given u=0 and s= 7 m and v=10 m/s
100= 2*a*7
a= 100/14
Force required(p)= ma = 50*100/14 = 357 N
….….….….….….….…..............................................

a=v²/2s
=>a=100/14=7.14 m/s²

F=ma=50*7.14=357.14 N
