Question

A car travel at 20km/h speed up 60km/h in 6 second what is it acceleration and what is distance travel

Answer 1

intial velocity= 20km/h=20*5/18=5.5m/s

final velocity=60km/hr=60*5/18=16.6m/s

t=6

a=v-u/t

=16.6-5.5/6=11.1/6=1.85m/s^2=a

distance=average speed/tim taken

=20+60/6

=13.3kms

please mark as brainliest

Answer 2

Explanation:

v = 60 km/h = 50/3 m/s

u = 20km/h = 50/9 m/s

t = 6 secs

using 1st eq of motion,
