Question

A car traveling at 10m/s comes to rest in 10s. Calculate its acceleration​

Answer 1

Answer:

deceleration = -1 m/s²

Explanation:

Velocity = 10 m/s

time = 10 s

Deceleration / negative acceleration = 10/10 = 1m/s².

Answer 2

Initial Velocity (u) = 10 m/s

Final velocity (v) = 0 m/s

Time taken (t) = 10 sec.

Acceleration = unknown

Acceleration (a) = (v - u)/t

= (0 - 10)/10

= -10/10 m/s^2

= -1 m/s^2

Hence, the acceleration produced by the body is -1m/s^2.
