A 4.14-g bullet is moving horizontally with a velocity of 358 m/s, where the sign indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface. Air resistance is negligible. The bullet passes completely through the first block (an inelastic collision) and embeds itself in the second one, as indicated in part b. Note that both blocks are moving after the collision with the bullet. The mass of the first block is 1224 g, and its velocity is 0.661 m/s after the bullet passes through it. The mass of the second block is 1567 g. (a) What is the velocity of the second block after the bullet imbeds itself

Jason and alejandro lift a chair 2 meters into the moving truck using 150 newtons of force. it takes them 3 seconds to lift the chair how much power did they use

In what direction does the medium move relative to the direction of the wave? explain.

Aparticle of mass m is projected with an initial velocity v0 in a direction making an angle α with the horizontal level ground as shown in the figure. the motion of the particle occurs under a uniform gravitational field g pointing downward. (a) write down the lagrangian of the system by using the cartesian coordinates (x, y). (b) is there any cyclic coordinate(s). if so, interpret it (them) physically. (c) find the euler-lagrange equations. find at least one constant of motion. (d) solve the differential equation in part (c) and obtain x and y coordinates of the projectile as a function of time. (e) construct the hamiltonian of the system, h, and write down the hamilton’s equations (canonical equations) of motion.
