Problem 7PE

A bullet is accelerated down the barrel of a gun by hot gases produced in the combustion of gun powder. What is the average force exerted on a 0.0300-kg bullet to accelerate it to a speed of 600 m/s in a time of 2.00 ms (milliseconds)?

Step-by-Step Solution:

Solution 7PE

Step 1 of  3

The average force exerted on the bullet can be calculated using Newton’s second law which relates the mass and acceleration of the bullet with the force exerted . where, m = mass of the bullet = 0.03 kg

a = acceleration of the bullet in m/s2.

Step 2 of  3

The acceleration of the bullet can be calculated  by taking the ratio of change in the velocity to change in the time. = where, v = v vo  t = t to

v and vo are initial and final velocity respectively.

t and to are initial and final velocity respectively.

Here,  v = 600 m/s and vo= 0 m/s

t = 2.00 ms = 2 10-3 s  and to= 0 s

So, = = = = 300000 m s-2

a  = 3 105 m s-2
