A slug with a mass of m=18g is fired out of a gun that has a length L=0.92m. The bullet spends t=0.16s in the barrel. Required:
a. Wwrite an expression in terms of the given quantities, for the magnitude of the bullets acceleration, a, as it travels through the rifle's barrel. You may assume the acceleration is constant throughout the motion.
b. What is the numerical value of the net force Fnet in newtons acting on the bullet.

Acricket ball of 70g moving with a velocity of 0.5 m/s is stopped by a player in 0.5s what is the force applied to stop the ball

Which body is in equilibrium? (1) a satellite orbiting earth in a circular orbit (2) a ball falling freely toward the surface of earth (3) a car moving with a constant speed along a straight, level road (4) a projectile at the highest point in its trajectory

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
