Given
v = 343 m/s
ac = 5g
ac = 5*9.8 m/s^2
ac = 49 m/s^2
where,
v: velocity
ac = centripetal aceleration
Procedure
We call the acceleration of an object moving in uniform circular motion—resulting from a net external force—the centripetal acceleration ac; centripetal means “toward the center” or “center seeking”.
Formula
The minimum radius not to exceed the centripetal acceleration is 2401 m.
Answer:
The magnitude of the average drag force is 2412.34 N.
Explanation:
Given that,
Mass of car
Velocity v = 25.8 m/s
Distance
Speed of car = 13.1 m/s
Height = 12.5 m
We need to calculate the magnitude of the average drag force
Using equation kinetic energy
Where, = initial velocity
= final velocity
h = height
g = acceleration due to gravity
=drag force
m = mass of the car
d = distance
Put the value into the formula
Hence, The magnitude of the average drag force is 2412.34 N.
