A hockey puck of mass
m = 0.170 kg is loaded into a spring gun with spring
constant k = 306 N/m. The spring is compressed by a
distance d = 0.100 m and then released, launching the puck
onto a horizontal and frictionless surface of ice with speed v in
the positive x-direction. This puck then collides with
another puck of the same mass which is at rest at the origin.
After the collision the two pucks move away...
a ball mass m=60g is shot with speed vi=22m/s into the barrel of a spring gum of mass M=240g initially a rest on a frictionless surface. the ball sticks in the barrel at the point of maximum compression of the spring. assum that the increase in thermal energy due to friction between the ball and the barrel is negligible. (a) what is the speed of the spring gun after the ball stops in the barrel?(b) what friction of the initial...
A 26 kg gun is standing on a frictionless surface. The gun fires a 55.2 g bullet with a muzzle velocity of 320 m/s. The positive direction is that of the bullet. Calculate the momentum of the gun immediately after the gun was fired. Answer in units of kg · m/s.
The spring of a spring gun has force constant k = 450 N/m and negligible mass. The spring is compressed 6.40 cm and a ball with mass 0.0270 kg is placed in the horizontal barrel against the compressed spring. The spring is then released, and the ball is propelled out the barrel of the gun. The barrel is 6.40 cm long, so the ball leaves the barrel at the same point that it loses contact with the spring. The gun...
The spring of a spring gun has force constant k = 400 N/m and negligible mass. The spring is compressed 6.00 cm and a ball with mass 0.0300 kg is placed in the horizontal barrel against the compressed spring. The spring is then released, and the ball is propelled out the barrel of the gun. The barrel is 6.00 cmlong, so the ball leaves the barrel at the same point that it loses contact with the spring. The gun is...
A massless spring of a spring gun has a force constant k=800 N/m. A ball of mass 0.5 kg is resting on top of the spring. The ball compresses the spring by d as shown in the right figure. When the gun is fired vertically, the ball reached a maximum height of 5 m from the top of the spring as it returns to its natural length. Calculate how much the spring was initially compressed (d). (a) 12 cm; (b)...
A ball of mass 0.20 kg is fired with velocity 120 m/s into the barrel of a spring gun of mass 2.0 kg initially at rest on a frictionless surface. The ball sticks in the barrel at the point of maximum compression of the spring. No energy is lost to friction. What fraction of the ball's initial kinetic energy is stored in the spring?
A ball of mass 0.45 kg is fired with velocity 120 m/s into the barrel of a spring gun of mass 2.0 kg initially at rest on a frictionless surface. The ball sticks in the barrel at the point of maximum compression of the spring. No energy is lost to friction. What fraction of the ball's initial kinetic energy is stored in the spring?
a 2.0 kg mass moves along a frictionless horizontal surface at a speed of 5.0 m/s. The mass encounters a 30 degree inclined surface with a constant friction force of 1.5 N. At 1 m high (vertical) the surface levels off and is again frictionless. the mass then encounters a spring with k=10 N/m a) how far is the spring compressed after the mass comes to rest? b) how far down the inclined plane will the mass move after bouncing...
