Question

please help me to get the answer​

Answer 1

Answer:

t = 2√5 or 4.47 second

Step-by-step explanation:

s = 100m

u = 0m/s

a = 10m/s^2

t = ?

By applying 2nd equation of motion

i.e. s = ut + 1/2(at^2)

so,

100 = 0(t) + 1/2(10)(t^2)

100 = 5t^2

t^2 = 100/5

t^2 = 20

t = √20

t = 2√5s

t = 4.47s
