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)?
ANSWER:
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.
