2 A Model Rocket Car With A Mass Of 0 2 Kg Is Launched Horizontally From An Initial State Of Rest When The Engine Is 1 (34.53 KiB) Viewed 29 times

(2) A model rocket-car with a mass of 0.2 kg is launched horizontally from an initial state of rest. When the engine is fired at 10 its thrust provides a constant force T-2N on the car. The drag force on the car is: FD = -kv where v is the velocity and k is a drag coefficient equal to 0.1 kg/s. (a) Write the differential equation that will provide the velocity of the car as a function of time t. Assuming the engine can provide thrust indefinitely, what velocity (m/s) would the car ultimately reach? (b) What would the velocity (m/s) of the car be after 2 seconds?
