3. A wooden block with mass 2.00 kg is placed against a compressed spring at the bottom of a slope inclined at an angle of 25.0° (point A). When the spring is released, it projects the block up the incline. At point B, a distance of 4.60 m up the incline from A, the block is moving up the incline at a speed of 6.35 m/s and is no longer in contact with the spring. The coefficient of kinetic friction between the block and incline is k = 0.45. The mass of the spring is negligible. Calculate the amount of potential energy that was initially stored in the spring.

A 2.00 kg mass on a frictionless incline plane of angle 6 degrees is released and begins sliding down the incline. At the bottom of the incline is a spring (k=70 N/m). If the mass slides 0.30 m along the incline plane before it contacts the spring, how far is the spring compressed by the mass? (round to the nearest hundredth)
2. An inclined plane of angle 0 = 20° has a spring of force constant k = 500 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in the figure. A block of mass m = 2.50 kg is placed on the plane at a distance d = 0.30 m from the spring. From this position, the block is projected downward toward the spring with speed v = 0.75 m/s. By what distance is the spring compressed when the block momentarily comes to rest m

5. Moumita is holding a mass m=0.50kg, which is connected to the bottom of a vertical spring with spring constant k=10.0ON/m. She is holding the mass in place at a height h=1.5m above the floor. The spring is relaxed in this condition. When Moumita lets go of the mass, how far will the mass fall before it turns around and starts to travel upwards?
5. Two 8.5 kg masses are hung from a horizontal surface by two (massless) springs, as shown in the figure. The top spring has a spring constant of 400 N/m, and the bottom spring has a spring constant of 200 N/m. How long is each spring in this configuration if they both have rest lengths of 6.0 cm?
Problem 5: A block of mass 4.2 kg is sitting on a frictionless ramp with a spring at the bottom that has a spring constant of 490 N/m (refer to the figure). The angle of the ramp with respect to the horizontal is 39⁰
In starting a game of pinball, the 44.7 g ball rests on a spring, of spring constant k = 18.8 N/m, that has been compressed by 0.0900 m. If the spring is released, how far up the pinball table (which is inclined at 39.0°) does the ball go before rolling back down again? You can assume it doesn't hit any obstacles on the way up.
A bowling ball is attached to a 2.91-meter long cable and hung from the ceiling. The cable is kept taut and the ball is raised to an initial height of 1.73 meters above the classroom floor. It is released from rest and allowed to swing as a pendulum. Determine its speed (in m/s) when it is at a height of 1.17 meters above the floor.

The block comes to rest after compressing an ideal spring with force constant k = 500 [N/m] attached at the top of the ramp. The initial and final position of the block is shown in the figure. What is the maximum compression d of the spring? A. 0.250 [m] B. 0.302 [m] C. 0.550 [m] Y2 = 2.00 [m]- = У1 30.0° D. 0.832 [m] Mk 0.500 [m]
A 1.20 kg block slides down a frictionless incline with a slope angle of 42.0°, starting from a height 2.30 m above the bottom of the incline. The incline meets a frictionless horizontal surface, at the end of which is a spring in its equilibrium position (k =460. N/m) used to stop the block. Find the maximum compression of the spring.
3. Imagine building a large pendulum by attaching one end of a 3.25-meter-long cable to the ceiling and the other end to a bowling ball that weighs 64.5 N. If you pull the ball to the side, it will swing back and forth in a circular arc. In one experiment you measure the speed of the swinging ball to be 4.25 m/s as it passes through its lowest point (when the cable is vertical). At that moment, find a. the magnitude and direction of the ball's acceleration b. the tension in the cable
A block of mass 1.6 kg is held against a horizontal spring so that the spring is compressed 17 cm. The block is released and it slides across the floor a distance of 3.4 m before it stops. The coefficient of friction between the block and floor is 0.185. Find the force constant of the spring.
