Answer:
As 28m/s = 28m/s
Explanation:
r = the radius of the curve
m = the mass of the car
μ = the coefficient of kinetic friction
N = normal reaction
When rounding the curve, the centripetal acceleration is
therefore
As 28m/s = 28m/s

Answer:
Explanation:
the maximum speed is reached when the drag force and the weight are at equilibrium, therefore:
To calculate the velocity after 100 meters, we can no longer assume equilibrium, therefore:
(1)
consider the next equation of motion:
If assuming initial velocity=0:
(2)
joining (1) and (2):
(3)
To plot velocity as a function of distance, just plot equation (3).
To plot velocity as a function of time, you have to consider the next equation of motion:
as stated before, the initial velocity is 0:
(4)
joining (1) and (4) and reducing you will get:
solving for v:
Plots:
