A lizard accelerates from 12.0 m/s to 40.0 m/s in 6 seconds. What is the lizard’s average acceleration?

Explanation:

Acceleration can be found using the following formula.

where is the final velocity, is the initial velocity and t is the time.

The lizard started at 12.0 m/s and accelerated up to its final velocity of 40.0 m/s in 6 seconds.

Therefore:

Substitute the variables into the formula.

Solve the numerator first and subtract.

Divide.

The lizard's average acceleration is 14/3 or 4.66667 m/s²

he kicked it 10 feet straight up into the air? i think this works.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
