With uniformly accelerated rectilinear motion, the speed of the body in 2 s decreased from 8 to 3 m / s. What is the body’s acceleration modulus?
To calculate the acceleration modulus of a given body, we use the following formula:
a = | V – V0 | / t, where V is the final velocity of the body (V = 3 m / s), V0 is the initial velocity of the body (V0 = 8 m / s), t is the time during which the velocity has decreased (t = 2 s).
Let’s do the calculation:
a = | 3 – 8 | / 2 = 2.5 m / s2.
Answer: The body acceleration module is 2.5 m / s2.
