Question

a car accelerates uniformly 18km per h to 36 km per h in 5 s. ​

Answer 1

18km per h = 5 m/s

to 36 km per h = 10 m/s

acceleration = v-u/t

= (10-5)/5

= 1 m/s^2

Answer 2

Answer:

given. = accń = 18km/hr. ×5/18 = 18 m/s

s = 36 km 36000m = 36×10³m

t = 5sec

by 2nd kinametic equation of motion

s = ut + ½at²

put the value get the answer
