Question

A caris initially at rest starts moving with a constant acceleration of 0.5 m/s2 and travels a distance of 5 m. Find

(i) Final velocity

(ii)The time taken​

Answer 1

(I)

`{ \bf{ {v}^(2) = {u}^(2) - 2as }} \\ {v}^(2) = {0}^(2) - (2 * 0.5 * 5) \\ {v}^(2) = 5 \\ { \tt{final \: velocity = 2.24 \: {ms}^( - 1) }}`

(ii)

`{ \bf{v = u + at}} \\ 2.24 = 0 + (0.5t) \\ { \tt{time = 4.48 \: seconds}}`
