The 12-cm-long nail is embedded into the wood wall on its half-length. You take a 2.7 kg hummer and strike the nail, completely embedding the nail into the wall. The initial speed of the hummer is 16 m/s. What is the average force acting on the nail?

A rifle with a barrel length of 59 cm fires a 9 g bullet with a horizontal speed of 420 m/s . The bullet strikes a block of wood and penetrates to a depth of 13 cm .What resistive force (assumed to be constant) does the wood exert on the bullet? ( I got 6100 N but I am not sure if this is correct). How long does it take the bullet to come to rest after entering the wood?

Please write clearly and each step. Thanks! Ballistic Pendulum– A 2.50 kg block of wood is suspended from the ceiling with a 0.6m length of wire of negligible mass. A bullet, whose mass is 10g, is fired into the block, and together they swing with an initial speed of 1.2 m/s. Ignore the effects of air resistance. a. What is the velocity of the bullet immediately before it hits the block? b. What is the magnitude of the average force...

Two metal plates are squares of 12 cm by 12 cm, separated by 1.0 mm of air. Wires connected to each plate are also connected to a 9.0 V battery. A proton (charge +1.6 x 10-19 C, mass 1.67 x 10-27 kg) is launched away from the negative plate, toward the positive plate, with an initial speed of 250 m/s. Which plate does the proton hit first, and how long does it take to hit that plate?

a)How long does it take an electron to move 50 cm, from rest, in a uinform E-field of 500 N/C? (The mass of an electron is 9.11X 10^-31 kg) b) An electron, initially at the origin, is projected into a uniform E-field (E=10000 N/C) that is oriented along the +y axis. If the initial velocity of the electron was 160 m/s along the +y axis, how long will it take for the electron to reach its maximum y position?
