Question

a car acquires a velocity of 72km/hr in 10 sec starting from velocity. find the acceleration and distance travelled in this time ?


plz answer fast​

Answer 1

Answer: acceleration= 2 m/s

distance=100 meters

Explanation:

Velocity=72 km/h= 20 m/s

Initial velocity=0 m/s

Time=10 seconds

1) Velocity=u+at

20=0+a x 10

72= a x 10

20/10=a

2=a

Therefore, a=2m/s²

2)s=ut+1/2at²

S=0 X 10 + 1/2 X 2 X 10 X 10

S= 10 X 10

S = 100 meters

Therefore, Distance= 100 meters
