Question

An object travel with speed of 72 km/h
applies break it stop after 10 sec
Find the acceleration s bus and
distance travelled by bus​

Answer 1

Answer:

the initial velocity of the object= 0m/s

the final velocity =72km/h

to convert 72km/h into m/s we have to multiply it with 5/18

= (72*5/18)m/s= 20m/s

the final velocity is 20m/s.

the acceleration= final velocity- initial velocity/time= 20-0/10= 2m/s²
