Question

A car is moving with the velocity of 10m/s speed up to 30m/sin 5 second . calculate its acceleration.

Answer 1

answer

Explanation

velocity=10m/s

time=5s

speed=30m/sec

a=

Answer 2

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,

v2=u 2+2as

v 2=10 2+2×5×30

v 2=100+300

v 2 =400 v = 400

v = 20 m/sec

_____________________________

ANSWER =

FINAL VELOCITY = 20 m/sec
