1. Moby travels down a halfpipe on his skateboard in five seconds. His speed at the bottom is 10 m/s. What was his
acceleration?

The acceleration of Moby will be 2m/s².

From the information, the following can be depicted:

Therefore, the acceleration will be:

Acceleration = Velocity / Time

Acceleration = 10m/s / 5

Acceleration = 2m/s.

The acceleration of Moby is 2 m/s²

Explanation:

Given:

Time, t = 5 seconds

Velocity, v = 10 m/s

Acceleration ,a = ?

We know:

On substituting the value we get:

Therefore, the acceleration of Moby is 2 m/s²

answer; i believe that the correct answer is (a); a large rock being weathered by wind and rain;

the dependant variable is spilled water

the independent is the heat
