Question

URGENT PLEASE... SAVE ME FROM THIS HW

An object at rest starts accelerating. If it travels 40 meters to end up going 20 m/s, what was its acceleration.

Answer 1

The car's acceleration is 5m/s^2

Step-by-step explanation:

acceleration is the change in velocity per unit time.

so this formula will work.

V^2= u^2 + 2as

20^2 = 0^2+ 2a (s)

Answer 2

Answer: The car's acceleration is 5m/s^2
^ 3.0
Explanation: The acceleration is the change in
velocity per unit time.
Here the initial velocity is O the final velocity is
20.
So this formula is applicable.
V^2= u^2 + 2as
20^2 = 0^2+ 2a (s)
