Question

What is the force exerted on a body of mass 1kg if its velocity changes from
60km/h to 80km/h in 1minute?​

Answer 1

Answer:

answer is  and 0.09 N

Explanation:

as given,in km/hr

change in velocity (delta v)= v2-v1=80*5/18-60*5/18=5.56m/s

time =1 min = 60 sec

f=ma

a=v/t=5.56/60=0.09m/s2

now by formula f=ma

mass =1 kg

a=0.09m/s2

f=1*0.09=0.09N
