Question

two cars of the same mass are moving with velocities v1 and v2 respectively. if they are stopped by suppling same breaking power in time t1 and t2 respectively then v1/v2 is

Answer 1

Answer:

Explanation:

final velocity is zeero for both the cars.v=0v = v1+a1t1a1 =v1/t1similarly a2 = v2/t2power = force.velocityp1 = ma1v1= mv12t1p2 = mv22t2p1=p2 mv12t1= mv22t2v1v2 = t1t2−−√
