6. Two masses mA = 2.0 kg and m³ = 5.0 kg are on incline and are connected by a string as shown bwlow. The coefficient of kinetic friction between each mass and its incline is µ = 0.30. If ma moves up, and må moves down, determine their acceleration. You are ignoring the masses of the pulley and the cord. [T5, C4] mB MA 21 510

Question
P1. Answer #6
SPH4U0: Forces Take-Home Assignment
Name:
4. Derive the equation for the maximum speed for a banked curve with friction. Show all work and add
explanations to the steps. If you do not explain your steps, you cannot get full marks. You will need a FBD.
[T5, C4]
5. Using the derived equation from the previous question, solve the following problem:
A race car is cornering a banked curve with r = 55 m at an angle of 40 degrees. If the car corners the banked
curve with a speed of 216 km/h, what is the minimum coefficient of friction required? [T4]
6. Two masses mA = 2.0 kg and m³ = 5.0 kg are on incline and are connected by a string as shown bwlow. The
coefficient of kinetic friction between each mass and its incline is µ = 0.30. If ma moves up, and me moves
down, determine their acceleration. You are ignoring the masses of the pulley and the cord. [T5, C4]
