Problema Solution

Why is the following situation impossible? Starting from rest, a charging rhinoceros moves 50.0 m in a straight line in 10.0 s. Her acceleration is constant during the entire motion, and her final speed is 8.00 m/s.

Answer provided by our tutors

here initial speed=0

       acceleration=constant

       a=v-u/t

      a=v/t

     s=1/2vt     (kinematic equation)

       =1/2*8*10

       =40m

but s=50m. so it is imposssible to cover 50 m in 10 s
