A spring loaded ballistic pendulum gun requires an increasing force to load. When loading a ball of mass 0.056 kg, the spring is compressed 9.00 cm, the gun is fully loaded, and the force required is 90.0 N.
1) Calculate the work required to load the gun.
2) find speed ball leaves gun
3) how high would ball rise if it was fired verticall upward(neglect friction)
what was the speed of the bullet at impact with block.
A turntable that spins at a constant 80 rpm takes 3.70s to reach this angular speed after it is turned on. Find its angular acceleration (in rad/s^{2}), suppose it to be constant, and the number of degrees it turns through while speeding up.
A small block of mass m = 1.5 kg slides, without friction, along the loop-the-loop track shown. the block starts from the point P a distance h = 54 m above the bottom of the loop of radius R = 17.0 m. What is the kinetic energy of the mass at the ..
