A toy car of mass 0.06 kg is propelled by a compressed spring as shown in the following figure. Treat the effect of air resistance and friction to be negligible. Include units as appropriate below. Path of the Car h Alternate path The spring, with a force constant of 250 N/m, is initially compressed by 4.0 cm. The car follows the track labelled "Path of the Car" that rises h = 17 cm above the starting point. (a) How fast is the car going before it starts up the slope? v_fa = (b) How fast is the car going when it is at the top of the slope? v_fb =

At this point, the potential energy stored in the compressed spring is converted into kinetic energy of the car. We can use the principle of conservation of energy to find the speed of the car. The potential energy stored in the compressed spring is given by the Show more…

A 100-g toy car is propelled by a compressed spring that starts it moving. The car follows the curved track in Figure 7.39. Show that the final speed of the toy car is 0.687 m/s if its initial speed is 2.00 m/s and it coasts up the friction less slope, gaining 0.180 m in altitude.
A 0.030 kg toy car is pushed back against a spring-based launcher. The spring constant of the spring is 222 N/m. The spring compresses 0.090 m. The total distance the car travels is 2.509 m. a. Determine the velocity of the car once it leaves the spring. b. Assuming no energy is lost to friction, the car now travels up a ramp that is angled at 40.0° above the horizontal. Determine the distance the car travels up the ramp. c. Friction now acts along the flat surface only (μ = 0.200). Determine the new height that the car reaches.

A car of mass m = 0.225 kg is pushed against and compresses a spring of force constant k = 104 N/m by an amount x = 0.115 m. The car is then released from rest and moves on a horizontal track to the right. The track eventually bends downward and then straightens out horizontally a distance h = 44.0 cm below the first horizontal section. Friction is negligible here. a. Find the speed of the car on the upper portion of the track (after separating from the spring). b. Find the speed of the car on the lower portion of the track.
