A simple pendulum having a bob of mass \( m \) is suspended from the ceiling of a car used in a stunt film shooting. The car moves up along an inclined cliff at a speed \( v \) and makes a jump to leave the cliff and lands at some distance. Let \( R \) be the maximum height of the car from the top of the cliff. The tension in the string when the car is in air is...
