A child goes down the slide,starting from rest. If the length of the slide is 2m and it takes the child 3 seconds to go down the slide,what is the child’s acceleration?

Answer:

[tex]0.44 m/s^2[/tex]

Explanation:

We have the following data:

- distance covered by the child: d = 2 m (length of the slide)

- time taken to cover this distance: t = 3 s

- initial velocity of the child: 0 m/s (he starts from rest)

So we can find the acceleration by using the equation:

[tex]d=ut+\frac{1}{2}at^2[/tex]

Where a is the acceleration.

Substituting the values and solving for a,

[tex]a=\frac{2d}{t^2}=\frac{2(2)}{3^2}=0.44 m/s^2[/tex]
