The initial speed of the body is 8 m / s. After 2 seconds, the speed decreased to 4 m / s. Determine the acceleration of the body.
| December 5, 2020 | education
The formula for finding the acceleration a = ΔU / t, where ΔU is the change in the speed of the body, and t is the time
ΔU = 8 – 4 = 4 m / s
a = (4 m / s) / (2 s) = 2 m / s ^ 2
Answer: 2 m / s ^ 2
