A bullet with a mass of 0.04-kg is traveling horizontally at 1400 m/s when it strikes a stationary target that is balanced on th

e top of a wooden post. The target has a mass of 9.96-kg. The target, with the bullet embedded, is knocked off of the post and moves to the right. How fast is the target with the bullet lodged in it traveling?

The speed of the target with the bullet lodged in it is 5.6 m/s.

<h3>What is speed?</h3>

This is the rate of change of distance.

To calculate the speed of the target and the bullet lodged, we use the formula below.

Formula:

V = mu/(m+M)............. Equation 1

Where:

V = Speed of the target and the bullet
m = mass of the bullet
M = mass of the target
u = Initial speed of the target

From the question,

Given:

m = 0.04 kg
u = 1400 m/s
M = 9.96 kg

Substitute these values into equation 1

V = (0.04×1400)/(0.04+9.96)
V = 56/10
V = 5.6 m/s

Hence, the speed of the target with the bullet lodged in it is 5.6 m/s.
