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
