Show all work please
The speed of a bullet as it travels down the barrel of a rifle toward the open end is given by: v-(-5.00 x 107)t2 + (3.00 x 1 jt where v is in m/s and t is in seconds. The acceleration of the bullet just as it leaves the end of the barrel is zero. a. Find the position x and acceleration a of the bullet as functions of time while it is still within the...

A 15.0-g bullet is fired at a muzzle velocity of 3250 m/s from a high-powered rifle with a mass of 4.75 kg and barrel of length 75.0 cm. (a) How long is the bullet in the barrel? (b) What is the force on the bullet while it is in the barrel? (c) Find the impulse exerted on the bullet while it is in the barrel. (d) Find the bullet’s momentum as it leaves the barrel. I've seen this question a...

Problem 4 1. An object with a mass m is attached to the free end of a light string wrapped around a reel of radius R and mass M. The reel is a solid disk, free to rotate in a vertical plane about the horizontal axis passing through its center (of mass) as shown in the figure below. The suspended object is released from rest h m above the floor. The entire system is...

A mass m = 10 kg rests on a frictionless table and accelerated from rest by a spring with spring constant k = 4490 N/m. The floor is frictionless except for a rough patch. For this rough patch, the coefficient of the kinetic friction is µk = 0.5. The mass leaves the spring with speed v = 2.8 m/s. Use work and energy to answer the following questions: (a) How much work is done by the spring as it accelerates...
