A 3.0 kg block slides with a speed of 2.3 m/s on a frictionless horizontal surface until it encounters a spring. If the block compresses the spring 5.6 cm before coming to rest, what is the force constant of the spring? What initial speed should the block have to compress the spring by 1.4 cm?
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)
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.
In order to stop a 15.0 kilogram block from sliding down a frictionless 40.0° incline, a powerful spring with k = 2.90 104 N/m is used. Blocks can travel up to 3.00 meters after they are released from their resting place against springs. How much of the spring's original tension will remain after the block comes to a halt?
A .500kg block attached to a spring with length .60m and force constant 40.0 N/m, is at rest with the back of the block at point A on a frictionless horizontal air table. The mass of the spring is negligible. You move the block to the right along the surface by pulling with a constant 20.0 N horizontal force. what's the block's speed when the black of the block reaches point B, which is 0.25 m to the right of point A.
A particle moves on the x axis under the influence of a force with x component given by: F.(x) = 5.0 N for 0 &rs 1.0 m; and F(x) = (8.0 –3.0x) N, for 1.0 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.
