Question

a racing car starting from rest and moving with uniform acceleration attains a speed 40 km per hour in 10 minutes find its acceleration​

Answer 1

Answer:

acceleration= final velocity - initial velocity/ time taken

speed=40x1000=40000m/s^1

time=10x60=600

40000-0/600

66.7m/^2

Explanation:

please mark me as brain list

Answer 2

Answer:

0.0185 m/s^2

Explanation:

U= 0 m/s   a=constant     V=40 km/hr      T=10X60=600 s

V= 5/18 x 40 = 11.1 m/s

V = UT + 1/2 AT^2

11.1 = 1/2(A)120000

11.1 = 6000 ( A)

A = 0.0185 m/s^2
