Question

A car increases its speed from 20km per h to 50km per h in 10 sec find it’s acceleration

Answer 1

hey dear
here is your answer

given data :

initial velocity (u) = 20 km/hr or 5.55 m/s

final velocity (v) = 50 km/hr or 13.88 m/s

time taken (t) = 10 seconds

to find : acceleration (a)

solution :

by using first equation of motion

v = u+at

13.88 = 5.55+10a

10a = 8.33

a = 0.833 m/s^2

hope it helps :)
