Question

If a fox starts from rest and accelerates at a rate of 1.1 m/s^2, how long does it take the fox to run 5 m A. 3.0s B. 4.5s C. 9.1s D) .22s

Answer 1

Given:
u=0 m/s
a=1.1 m/s^2
S=5 m
t=time it takes to run 5 m

Use the kinematics equation
S=ut+(1/2)at^2
=>
5=0*t+(1/2)1.1(t^2)
solve for t
t=sqrt(5*2/1.1)=3.015 seconds.
