A car accelerates from rest to a speed 20 m/s in 12 s. Find the distance the car travels this time
Andrew [12]
The first thing we need to do is figure out what equation to use. We will use the following kinematic equation...

Δx = (final velocity + initial velocity) x time / 2

We know that the car accelerates from rest, so initial velocity = 0 m/s
We also know final velocity = 20 m/s and time = 12s

Now we just need to plug everything in.

Δx = (20 x 12)/2 = 120 meters

10. Calculate the kinetic energy of a running back that has a mass of 80 kg and
EastWind [94]

Answer:

The answer is

<h2>2560 J</h2>

Explanation:

The kinetic energy of an object given it's mass and velocity can be found by using the formula

KE =  \frac{1}{2} m {v}^{2}

where

m is the mass

v is the velocity

From the question

m = 80 kg

v = 8 m/s

The kinetic energy is

KE =  \frac{1}{2}  \times 80 \times  {8}^{2}  \\  = 40 \times 64

We have the final answer as

<h3>2560 J</h3>

Hope this helps you
