ANSWER

What will be the stopping distance if the intial velocity is double?

Posted by Kajal Vishwakarma 4 years, 6 months ago

CBSE > Class 11 > Physics

1 answers

Yogita Ingle 4 years, 6 months ago

If the initial velocity is doubled, Then the stopping distance become 4 times.
From the third equation,
$v^2=u^2-2as$
$u^2= v^2+2as$
From this equation distance (s) is directly proportional to u^2.

ANSWER

A race car accelerates on a straight road from west to a speed of 180 km/h in 25 s Assuming uniform aceeleration of the car throughout Find the distance covered inthis time ?

Posted by Priyanshi Kumawat 4 years, 6 months ago

CBSE > Class 11 > Physics

3 answers

Gaurav Seth 4 years, 6 months ago

Speed after 25 s = 180 km/h = 180 ×(5/18) m/s = 50 m/s

From equation v = u + a t , we get acceleration. where v is final speed, u is initial speed which is zero because

the car strats from rest, a is acceleration and t is time taken to attain the final speed.

hence v = a t or 50 = a×25 or acceleration a = 50/25 = 2 m/s² .

distance travelled, S = (1/2)a t² = (1/2)×2×25×25 = 625 m
