You have developed a prototype and would like to collect some baseline data about a CO2 powered car. Specifically you want to know how far the car will travel. The manufacturer of CO2 cartridge you're using claims that the cartridge provides and average force of 5.1 N. The mass of your prototype (with cartridge) is 112g. In separate experiment, you determined the coefficient of friction for your car to be 0.12. On your first test of the car, you measure that it travels 2.00m during the interval of time when the cartridge is applying force to the car. Unfortunately, some furniture got in the way of your car further down the track, so you would like to calculate how far the car would have travelled if its motion hadn't been stopped. Calculate the distance it travels.
A 8.40 kg object oscillates at the end of a vertical spring that has a spring constant of 2.45 multiply.gif 104 N/m. Calculate the frequency of the dampened oscillation
According to kinematics(x=.5g*t2), the acceleration is dependant only upon. The mass of the object.
