Average acceleration: velocity/time
5/4= 1.25 m/s² Acceleration
Hope I helped :)
Answer:
V=22.4m/s;T=2.29s
Explanation:
We will use two formulas in order to solve this problem. To determine the velocity at the bottom we can use potential and kinetic energy to solve for the velocity and use the uniformly accelerated displacement formula:

Solving for velocity using equation 1:

Solving for time in equation 2:

There must be a conducting wire and electromotive force or free electrons
The initial speed of the vehicle before the collision is 8 m/s.
- Let the mass of the vehicle = m
- Let the initial speed of the vehicle stopped = u
- The initial speed of the vehicle parked at the red light = 0
<h3>Principle of conservation of linear momentum</h3>
- The initial speed of the vehicle before the collision is calculated by applying principle of conservation of linear momentum as follows;

Thus, the initial speed of the vehicle before the collision is 8 m/s.
