Question

15. A car starting from rest accelerates uniformly along a straight line. If it attains a velocity of
120 kmph in 12s, what is the acceleration of the car in m/s??​

Answer 1

Answer:

10m/s

because velocity = dispalacement / time

so , 120kmph/12s = 10

Explanation:

Answer 2

Answer:

25/9ms^2

Explanation:

v=u+at

u=0 as car start from rest

t=12 sec

12×5/18(change kmph into mps) =a×12
