Q. A bullet of mass 7.8 x10-3 kg moving at 1310 m/s impacts with a large fixed block of wood and travels 3.00 cm before coming to rest. Assuming that the deceleration of the bullet is steady, determine the force exerted by the wood on the bullet.
Quadrupole moments in the shell model
A 1.50 multiplied by 103kg car starts from rest and accelerates uniformly to 18.50m/s in 13s. Assume that air resistance remains constant at 400N during this time.
A more realistic car would cause the wheels to spin in a manner that would result in the ground pushing it forward with a constant force (in contrast to the constant power in Part A). If such a sports car went from zero to 30.0 in time 1.10 , how ..
A 240g block is attached to a horizontal spring and executes simple harmonic motion with a period of 0.150 s. If the total energy of the system is 3J.
A 10 m beam of mass 330 kg extends over a ledge. The beam is not attached, but simply rests on surface. A 53 kg student intends to position the beam so that he can walk to the end of it. How far from the edge of the ledge can the beam extend.
The 200 g head of a golf club moves at 40 m/s in a circular ARC of 1.2 m radius. How much force must the player exert on the handle of the club to prevent it from flying out of her hands at the bottom of swing? Ignore the mass of the club's shaft.
Two mirrors meet at a 133° angle. If light rays strike one mirror at 40°, at what angle ? do they leave the second mirror?what is the value of h.
A particle of mass M decays into two identical particles each of mass m, where m = 0.4M. Prior to the decay, the particle of mass M has a total energy of 4 Mc2 in the laboratory reference frame. The velocities of decay product are along the directi..
what is the electrostatic force that acts on this charge. What would be the least speed required for the rest of the trip to arrive in time for the interview.
A stone is dropped at t = 0. A second stone, with 6 times the mass of the first, is dropped from the equivalent point at t = 59 ms. (a) How far below the release point is the center of mass of the two stones.
what is the minimum coefficient of static friction required between tires and race track if the car is to stay on the track at a speed of 130m/s.
If the baseball exerts the force of 464N on the glove such that the glove is displaced 5.9 cm, how much work is done by the ball.
