Question

A car starts with velocity 10 m/s and accelerates​

Answer 1

Answer:

Initial Velocity (u) = 10 m/sec

Acceleration (a) = 5 m/sec

2

Distance (s) = 30 m

Final velocity (v) = ??

Using Newton's Third law of Motion,

v

v =

400

v = 20 m/sec

Answer 2

Answer:

as the given u-10m/s

acceleration a-5m/s²

distance s-30 m and velocity (v) x

using v²-u^=2as

x²-10²=2×5×30

x²-100=300

x²=400

x=20m/s

so velocity is =20/ms

and using v=u+at we get time

20 second
