Question

A baboon steals an apple and runs to a nearby boulder 10.0 m to its left. The baboon reaches the boulder in 1.0s with a constant acceleration of 20.0m/s^2 leftward. What was the baboon's initial velocity when it started running to the boulder?

Answer 1

Answer:

0

Step-by-step explanation:

its what khan academy said

Answer 2

Answer:

Initial velocity is zero.

Step-by-step explanation:

According to second equation of motion

    $s=ut+\frac{1}{2} at^2$

where s = distance traveled  

           t = time taken

          a = acceleration

          u = initial velocity

here in the question we have

      s = 10 m

     t = 1 second

    a = 20$ms^{-2}$

plugging the known value in order to find the unknown which is u (initial velocity)

[tex]10=u(1)+\frac{1}{2} (20)(1)^2[/tex

10 = u +10

gives u =0

therefore initial velocity is zero.
