First see the given values
a = 2m/s^2
t = 5 s
u = 0
v = ?
we know that
v = u + at
v = 0 + 2*5
v = 10m/s
now we have yo calculate the distance
S = ut + 1/2at^2
S = 0*5 + 1/2 * 2 *5^2
S = 25m
we have distance(S) = 100m
a = 2m/s^2
u = 0
so by the formula
S = ut + 1/2 a t ^2
100 = 0*t + 1/2 * 2* t^2
100 = t^2
t = 10s
hope it helps
