1a,b,c Energy Practice PHY-203 Page 1 of 4 Name: 1. An initially stationary block of mass 0.25 kg is launched horizontally by a spring of spring constant 600 N/m which is initially compressed 10 cm from its equilibrium position. The block travels along a rough, horizontal surface to the base of a frictionless incline angled 30° above the horizontal. The block rises l m vertically up the incline before momentarily coming to a rest. (a) How much work was done...
Question: An initially stationary block of mass 0.5kg is on an incline angled 20° above the horizontal. When released, it slides down the frictionless incline undergoing a vertical displacement of 4m and then travels across a rough horizontal surface to a spring constant 600 N/m. The block compresses the spring 20 cm from its equilibrium position before momentarily coming to a stop. A.) How fast was the block moving when it was at the base of the incline? B.) How...
An initially stationary block of mass 0.5kg is on an incline angled 20° above the horizontal. When released, it slides down the frictionless incline undergoing a vertical displacement of 4m and then travels across a rough horizontal surface to a spring constant 600 N/m. The block compresses the spring 20 cm from its equilibrium position before momentarily coming to a stop. D.) Naturally after momentarily stopping on the incline, the block will slide back down. Does it make it to...
A block of mass 3 kg is pushed against a spring of spring constant 3000 N/m. Initially, the spring is compressed by a distance of 0.220 m, when the block is released from rest and travels along a horizontal frictionless surface before encountering a frictionless ramp, inclined at an angle of 37° above the horizontal. How far along the ramp does the block travel before momentarily coming to rest?
magnitude 7. An initially stationary block of mass m is on a floor. A force of acceleration due to gravity) is then applied at an angle of θ-20° to the oseontal, What is the magnitude of the acceleration of the block across the floor if p, 0.620 and p 0530 A) Om/s B) 005 m/s C) 2.17 m/s D) 0.20 m/s' E) 20 m/s 28. The same heavy wooden block is dragged by a force F along a rough steel...
question 1 A block of mass m is pulled at constant velocity along a rough horizontal floor by an applied force � as shown. What is the magnitude of frictional force? Write your answer in terms of m, g, T, or q. question 2 An 8000-N car is traveling at 12 m/s along a horizontal road when the brakes are applied. The car skids to a stop in 4.0 s. How much kinetic energy does the car lose in this...
g=10 pi =3 B) C) 2 2mg 4 For Q6 to 08: A block of mass m is released from rest from a spring Q6. Find the work done by friction on of constant k that has been compressed a distance L. The block leaves the spring at x=0 when the spring has its normal length. The track the block as it travels from x=0 to x=D. shown has friction only between x=0 and x=D with a coefficient of mgAD...
1. An unknown mass (mı) on a rough horizontal surface is attached by a wire that passes over a massless, frictionless pulley to a 2.50kg mass (m2) as shown below. The bottom of the hanging mass is 1.50m above the floor. The system is released from rest at t-0s and the 2.50kg mass strikes the floor 0.82s later. The system is now returned to its initial position and a 1.20kg mass is placed on top of the block of mass...
