A particle is moving with initial velocity 40m/s along positive X-axis. Acceleration is -10m/s2. It starts from x =10 m. Find out maximum co-ordinate of particle in positive direction. (a) 90 m (b) 0 m (c) 120 m (d) 30 m.
Here,u=40m/s,For the maximum coordinate,v=0 and a=-
Now,by using
Since the particle starts from x=10m,so the maximum distance or coordinate from the origin=80+10=90m
