1.	A car moving with speed of 50 m/s ,can be stopped by brakes after at least 6m. if the same car is moving at a speed of 100m/s, the minimum stopping distance is
Answer» ANSWER If FINAL velocity is zero and ACCELERATION is −ve then. s= 2a/u ^2 s∝u ^2 So, if the velocity is doubled than stopping distance will become 2 2 =4 =6×4 *=24 m*.

ANSWER

If FINAL velocity is zero and ACCELERATION is −ve then.

s= 2a/u ^2

s∝u ^2

So, if the velocity is doubled than stopping distance will become 2

=4 =6×4

=24 m.
