a rifle is fired straight up and the bullet leaves the rifle with an initial velocity magnitude of 630 m/s. after 5.00 s, the velocity is 580 m/s. at what rate is the bullet decelerated?

Respuesta :

The rate at which the bullet decelerated is -10m/s²

Acceleration and deceleration

The formula for calculating the deceleration of an object is referred to as:

Deceleration = initial velocity-final velocity/time

Substitute the given parameters to have:

Deceleration = 580-630/5

Deceleration = -50/5

Deceleration = -10m/s²

Hence the rate at which the bullet decelerated is -10m/s²
