The angle of banking for a cyclist taking a turn at a curve is given by tan where symbols have their usual meaning. The value of n is:
1. | 1
|
2. | 2
|
3. | 3
|
4. | 4 |
A car of mass \(1000\) kg negotiates a banked curve of radius \(90\) m on a frictionless road. If the banking angle is of \(45^\circ,\) the speed of the car is:
1. | \(20\) ms-1 | 2. | \(30\) ms-1 |
3. | \(5\) ms-1 | 4. | \(10\) ms-1 |
The banking angle for a curved road of radius \(490\) m for a vehicle moving at \(35\) m/s is:
1.
2.
3.
4.
A car is moving in a circular horizontal track of radius 10 m with a constant speed of 10 m/sec. A plumb bob is suspended from the roof of the car by a light rigid rod of length 1.00 m. The angle formed by the rod with respect to the vertical is:
1. | Zero | 2. | 30° |
3. | 45° | 4. | 60° |
