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.
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...
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 toy car starts at rest on a circular track of radius 2.30 m. If it uniformly increases speed to 1.70 m/s in 3.10 seconds, find the magnitude of the acceleration of the car at the very end of the trip.
A 3-kg toy car sits at the highest point of a 13-meter-high hill. The car begins to roll down the slope from rest. Assuming the car coasts freely, without any friction or air resistance, what is the car's speed at each of the indicated points? Use for the acceleration due to gravity, g - 9.80 m/s* Note: the diagram below is NOT to scale. Car's speed Car's speed Number Number m/s m/s 13 m r's speed Number 2 m 6...
A car on a roller coaster starts at zero speed at an elevation above the ground of 20.8 m. It coasts down a slope, and then climbs a hill. The top of the hill is at an elevation of 14.77 m. What is the speed, in m/s, of the car at the top of the hill? Neglect any frictional effects; g=9.80 m/s2. A projectile is shot from the surface of Earth by means of a very powerful cannon. If the...
