I performed a lab using a toy car to go down a ramp that was positioned at different heights. For expample: ramp height = 60 cm, ramp length = 121.92 cm, time car took to clear the ramp from start = .67 seconds, distance car traveled from end of ramp to stopping point = 1178.56 cm, mass of car = .54 kg, based on this information......
Calculate the Work = F x d done by gravity that pushes the car down the ramp. Which d (distance) do you use and why?
Analyze the following figure.
The component of the gravitational force that is pushing the car down can be represented as,
Here, m and θ represent the car’s mass and the ramp’s angle, respectively.
The ramp’s angle can be determined as,
Here, h and l represent the ramp’s height and the ramp’s length, respectively.
Thus,
Substitute the relevant values.
