Q.1) A 5.8-g bullet travelling at 440 m/s strikes a large wooden fence post. If an average force required to stop the bullet was 4.5 x 10^3 N, how far into the fence post did the bullet penetrate?
2) You work for a moving company and are given the job of moving two crates (masses are 130kg and 280kg) held together by a rope attached between the two. You pull on a rope attached to the larger crate giving the system the acceleration of 0.29m/s2. What is the tension in each rope?
What is the angular velocity in rad/s . What is the least pressure obtained inside the bottle? What will happen when this pressure is reached.
Now a peg is placed 4/5 of the way down pendulum's path so that when the mass falls to its vertical position it hits and wraps around the peg. As it wraps around the peg and attains its maximum height it ends a distance of 3/5 L below its starting po..
An object of mass m is attached to a horizontal spring, stretched to a displacement A from equilibrium and released, undergoing harmonic oscillations on a frictionless surface with period T0. The experiment is then repeated with a mass of 4m. The sub..
