Question

99- | A person is riding a bicycle with uniforn
velocity. He applied brakes and stops in 10sec.
What of the accelration. The person weights
60kg and the, retarding force is 600N.
find the
initial velocity?​

Answer 1

Answer:

initial velocity u= 100m/s

Explanation:

F= m×a

Here,F= -600N,m= 60kg so,

a= -600/60= -10m/s^2

now,as a= v-u/t

-10= 0-u/10

0-u= -100

u= 100m/s
