A part of a childrens game is a launcher that consists of a spring, k=75 N/m, that is initially suppressed by 10 cm. After a trigger releases the spring, it pushes a uniform wooden ball of mass m=0.8 kg and radius r= 2 cm, the ball starts rolling without slippage on a horizontal track. The speed of the center of mass of the ball is

A projectile launcher as shown in the Figure is used to launch 0.5 kg ball into the air. The launcher is connected to a 1kg mass and starts from rest with the spring compressed to a length of 15 cm. The un-stretched length of the spring is 75 cm. When the launcher is released from rest, the 1kg mass will impact the ball and the ball wil project in the air. Determine a suitable spring constant and angle 8 for...

Problem 5 A spring with a spring constant k=200 N/m is used as a launcher for a small block whose mass is 10 g. The block is placed against the compressed spring in a horizontal arrangement on a smooth horizontal surface. The spring, with the block, is compressed 5 cm and then released. a) Find the speed of the block just as it leaves the spring b) The block encounters a rough surface as it leaves the spring. How much...

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)...

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...
A block of mass m = 4.5 kg is attached to a spring with spring constant k = 710 N/m.
A block of mass m = 4.5 kg is attached to a spring with spring constant k = 710 N/m. It is initially at rest on an inclined plane that is at an angle of θ = 25° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk=0.18. In the initial position, where the spring is compressed by a distance of d = 0.12 m, the mass is at its lowest...
A block of mass m = 3.5 kg is attached to a spring with spring constant k = 780 N/m
A block of mass m = 3.5 kg is attached to a spring with spring constant k = 780 N/m. It is initially at rest on an inclined plane that is at an angle of θ = 28° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. In the initial position, where the spring is compressed by a distance of d = 0.19 m, the mass is at...

a steel cable
A mass-less spring having a spring constant k = 187 N/m, is inside a horizontal barrel. Its left end is rigidly fixed at position x = 0.0 cm, and its right end is at X L, where L -18.8 cm. The spring is then squeezed so that the right end of the spring is at X = S, where 5 - 14.8 cm. A ball of mass 56 g is put in front of the spring, and...

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...
