A 0.19 kg mass is held at rest against a compressed spring with a spring constant of 103 N/m. When released, the mass leaves the spring with a speed of 6.28 m/s. Assuming that the spring force if wholly responsible for changing the motion of the mass, by what distance was the spring initially compressed from its equilibrium position?
4) A 100 gram toy car is propelled by a compressed spring, as shown in the figure. The car tollows a track that ries 18 cm above the starting point. The toy car is released from the spring with a speed of energy of the car when the car is released from spring: tb) kinetic energy of thea 5m/s., find (a) the kinetic the to of the sope. speed of the car at the top of the slope. Path of...
PHYS1030 Newtonian Mechanks QUESTION #10: A 22-kg block is held a rest against a spring of force constant k # 930 N/m as shown below. Initially the spring is compressed a distance of 15 em. When the block is released, it slides across a surface that is frictionless except for a rough patch of width 60.0 cm that has a coefficient of kinetic friction μ.-0.34. Find the block's speed (m/s): (a) before crossing the rough patch b)after crossing the rough...
Ball A (m 0.5 kg, I 0.7 MR2) is held at rest against a spring, compressed by a distance x-40 cm. The ball is released and move along a frictionless surface (Ho 4 m) until it collides with ball B (m- 0.25 kg, I- 0.5 MR2) which is at rest. After the collision, the two balls roll down a track (which has friction!) and leaves the track at a height, H,- 1m. Ball B goes to a height of HB-5m...
A toy car of mass 0.620 kg is pressed against a spring. The spring constant is 250 N/m and the spring is compressed a distance of 0.031 m. How fast is the cart moving after it's released from the spring? Ignore the effects of friction.
A toy car of mass 1kg is pushed up against a spring with a spring constant of 500N/m, compressing the spring 0.05m. The spring is released, causing the car to slide across a frictionless track. After a certain distance of track, the car slides up a frictionless ramp of 10 degrees before coming to a stop. a) What is the speed fo the car after it leaves the spring but before it starts up the ramp. (Answer: 1.12m/s) b) What...
A 1 kg toy car is propelled by a compressed spring that starts it moving. The car follows the curved track. What is the initial speed of the car that having gained 0.3 m in altitude has a speed of 2.0 m/s. You may assume the work due to friction along the track is 1 J.
Part B (Mechanical Energy and Conservation of Energy) Problem B1: A block of mass m = 0.2kg is held against but not attached to a spring of so compressed by 20cm, as show below. When released, the block slides som the rough incline before coming to rest. but not attached to a spring of stiffness constant ka 50cm 20cm * = 0, Usp = 0 Low Ug = 0 Use mechanical energy for non-conservative force to find: 1) The force...
Two blocks on a friction less table are held at rest with a compressed spring between them. When the blocks are released, the spring pushes them apart and they move in opposite directions. The spring has a spring constant of 215 N/m. One of the blocks moves away at 0.45 m/s while the other moves away at 0.90 m/s. The heavier of the two blocks has a mass of 1.4 kg. How far was the spring compressed in m?
A 50g toy car is spring loaded to propel forward when released. If the spring is stretched a distance of 2cm and has a K value of 500N/m. Calculate the speed at which the toy will move when the spring is released.
