Acceleration and deceleration and momentom
they slow the car down and it loses momentome
<h3><u>Answer;</u></h3>
= 4.5 * 10^2 joules.
<h3><u>Explanation;</u></h3>
- A perfectly elastic collision is a type of collision in which kinetic energy is conserved.
- Therefore, to calculate the kinetic energy of the system after the collision we use the formula 1/2 mv²
Mass = 25 kg
Velocity = 5.98 m/s
KE = 1/2 × 25 × 5.98 ²
= 447 Joules
This translates to about <em><u>4.5 ×10^2 Joules</u></em>
