Situation 3. A road having a radius of 120m and has angle of 9.31 degrees from the horizontal. The center of gravity of the car is located 0.80m above the roadway and the distance between the two front wheels is 1.20m. If the car has a total weight of 15 KN,
a. Compute the normal acceleration and the velocity of the car before overturning.
b. If uk= 0.60, what is the velocity of the car without sliding?
Please answer this with a complete solution and with a Free Body Diagram PLEASE. Thank you.
Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE.
A motorist is about to enter the exit ramp of a highway. When it is 50m before reaching A (along the straight path), the motorist travels at 80km/h, decreasing at the rate of 0.5m/s2until it reaches B. After it reaches B, it travels at a constant speed. Determine the magnitude of the acceleration:
just after A
just before B
just after B
