Answer:
80 km
Explanation:
Since 240 divided by three is 80, the velocity the car is traveling at is 80 kilometers per hour.
Answer:
1472.98 m
Explanation:
Data provided:
Speed of circular looping, v = 340 m/s
Acceleration, a = 8g
here,
g is the acceleration due to the gravity = 9.81 m/s²
Now,
the centripetal acceleration is given as,
r is the radius of the loop
on substituting the respective values, we get
or
r = 1472.98 m
Close the switch would be the correct answer
