A spring with constant k=200 N/m is fixed to the top of an incline that makes an angle of 40.0 degrees with the horizontal. A projectile with mass 1.10 kg is projected up the plane, form an initial horizontal position that is d from the end of the uncompessed spring. a) If the incline is frictionless and the initial kinetic energy of the projectile is 17.0 J, how much will the spring be compressed? b) If there is a coefficient of friction of 0.200 and the spring must compress by 1.50 cm at the moment when the projectile stops (say, to trigger an event like a switch) then what must the initial speed of the projectile be? All other conditions are same as in the setup.
A spring is attached to an inclined plane as shown in the figure. A block of mass m = 2.31 kg is placed on the incline at a distance d = 0.279 m along the incline from the end of the spring. The block is given a quick shove and moves down the incline with an initial speed v = 0.750 m/s. The incline angle is 0 = 20.0°, the spring constant is k = 455 N/m, and we can assume the surface is frictionless. By what distance (in m) is the spring compressed when the block momentarily comes to rest? m 8 ww 0.038 X Apply the work-energy theorem. The force of gravity does positive work on the block as it slides down the incline through the total distance (d + x), and the spring force does negative work on the block as it slides through distance x. Note that the block has initial kinetic energy but the final kinetic energy is zero. Take the zero level of gravitational potential energy to be where the block momentarily comes to rest. m
A 2.0 kg block is pressed up against a spring (k = 44 N/m) that is attached to a wall as shown. The block is held so that there is 1.2 J stored in the spring and then the block is released from rest. If there is no friction, what is the speed of the block when the energy stored in the spring is 0.0 J?

An inclined plane of angle e = 20.0° has a spring of force constant k = 520 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in the figure below. A block of mass m = 2.45 kg is placed on the plane at a distance d = 0.288 m from the spring. From this position, the block is projected downward toward the spring with speed v = 0.750 m/s. By what distance is the spring compressed when the block momentarily comes to rest?

Below is a conservation of energy problem. The solution to this problem is provided. Assess whether the solution provided is correct or incorrect AND EXPLAIN WHY. = 4.6 kg block is at rest against a horizontal spring that is compressed by 0.40 m. The spring has a spring constant of k₁ 2750 N/m. After leaving the spring, it travels up a 28° incline to a height of 2.8 m. At the top of the hill is a second spring with a spring constant of k₂ = 350 N/m. The horizontal portions are frictionless, but the hill has a coefficient of kinetic friction equal to uk = 0.16.

Your answer is partially correct. Try again. In the figure, a spring with spring constant k = 180 N/m is at the top of a frictionless incline of angle e = 38°. The lower end of the incline is distance D = 0.92 m from the end of the spring, which is at its relaxed length. A 1.5 kg canister is pushed against the spring until the spring is compressed 0.22 m and released from rest. (a) What is the speed of the canister at the instant the spring returns to its relaxed length.(which is when the canister loses contact with the spring)? (b) What is the speed of the canister when it reaches the lower end of the incline?

Part 1. A 3 kg package of tamales (see the figure below) slides along a floor with speed v1 = 5 m/s. It then runs into and compresses a spring, until the package momentarily stops. Its path to the initiallyrelaxed spring is frictionless, but as it compresses the spring, a kinetic frictional force from the floor, of magnitude 15 N, acts on the package. If k = 8 000 N/m, by what distance d is the spring compressed when the package stops? What makes up the system in this problem and state a reasonable assumption about this system? Consider the following for a rotational motion:r = 6 m, θ = 0.5t2, where t is in seconds and θ is in radians.Find the magnitudes of (a) tangential acceleration at t = 4 s, and (b) radial acceleration at t = 4 s.[1+1]
