The fiqure below shows a solid cube with a mass m on an inclined plane, at angle e above horizontal. R The cube is attached at one end to a spring with spring constant k at one end and a lightweight string at the other. The string is in turn wound around a reel with a radius R and moment of inertia I. The axle of the reel and the incline both have negligible friction The reel is turned counterclockwise...

A ball is thrown straight up with an initial speed of v m/s. The ball was released 1.2 m above the ground, but when it returns back down, it falls into a hole 14.2 m deep. If the ball’s speed at the bottom of the hole is 28 m/s, what was the initial speed v (in m/s) of the ball?

A box of mass m is pressed
against (but is not attached to) an ideal spring of force constant
k and negligible mass, compressing the spring a distance x. After
it is released, the box slides up a frictionless incline as shown
in the figure and eventually stops. If we repeat this experiment
but instead compress the spring a distance of 2x.
A spring-loaded toy gun is used to shoot a ball of mass m=1.50 kg straight up in the air
A spring-loaded toy gun is used to shoot a ball of mass m=1.50 kg straight up in the air, as shown in (Figur 1) . The spring has spring constant k =667 N/m. If the spring is compressed distance of 25.0 centimeters from its equilbriurn position y = 0 and then released, the ball reaches a maximum height hax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of...

2. A block with mass m is forced against a horizontal spring of 100 N/m negligible mass, compressing the spring a distance d (Figure 1). When released, the block moves on a horizontal tabletop a length L before coming to rest. The spring has a force constant k. What is the coefficient of kinetic friction between the block and the tabletop? Express your answers in terms of any or all of the variables m, d, g, L and k. B)...

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 spring, of negligible mass and which obeys Hooke's Law,
supports a mass M on an incline which has negligible friction. The
figure below shows the system with mass M in its equilibrium
position. The spring is attached to a fixed support at P. The
spring in its relaxed state is also illustrated. Mass M has a value
of 255 g. Calculate k, the spring constant. The mass oscillates
when given a small displacement from its equilibrium position along
the...

A spring-loaded launcher is used to shoot a ball of mass 1.50 kg straight up in the air, as shown in (Figure 1). The spring has spring constant k 667 N/m. If the spring is compressed a distance of 25.0 centimeters from its equilibrium position y = 0 and then released, the ball reaches a maximum height hmax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of the...

A block of mass m is pushed against an ideal spring of constant of k, compressing it over a distance x with respect to its natural length. When the block is released, it moves up a rough ramp of inclination θ and coefficient of friction μk.What is the maximum distance (d) that the block travels up the incline? You MUST use conservation of energy to solve this problem. Epress your answers in term of m, g, k, μk and θ.

A spring-loaded toy gun is used to shoot a ball of mass m=1.50kg straight up in the air, as shown in (Figure 1) . The spring has spring constant k=667N/m. If the spring is compressed a distance of 23.0 cm from its equilibrium position y=0 and then released, the ball reaches a maximum height hmax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of the gun. Assume that...
