u = 5m/s , a = 0.2m/s^2 , t = 10sec , v = ? , s = ?
From 1st equation of motion ,
v = u + at
where v is final velocity , t is time , a is acceleration , u is initial velocity
=> v = 5 + 0.2(10)
=> v = 5 + 2 = 7m/s
From second equation of motion ,
v^2 - u^2 = 2as
where v is final velocity , u is initial velocity , a is accleration , s is distance
=> 7^2 - 5^2 = 2(0.2)(s)
=> 24 = 0.4 (s) => s = 60m
