Question

A car traveling at a speed of 25 m/s decreases its speed to 20.0 m/s in 10 seconds. What is the magnitude of its acceleration

Answer 1

Answer:

acceleration = (final speed - initial speed)/time

Answer 2

Explanation:

As given:

As given:Speed intial =25m/s

As given:Speed intial =25m/sFinal Speed =20m/s

we know acceleration = change in speed/time

so ∆V=5

t=10 seconds given

t=10 seconds given |a|=5/10

t=10 seconds given |a|=5/10=1/2 m/s²

So the answer is 1/2 m/s²
