Answer:
Length of the Pendulum is 14.4 cm
Explanation:
Time period of simple pendulum is given by
time taken for one oscillation is
Pendulum length on the earth surface is
Length of the Pendulum is 14.4 cm
The time elapsed when the vehicles are closest to each other is 20 min.
The given parameters:
- Speed of the truck, u = 80 km/h
- Distance, d = 32 km
- Speed of the car, v = 50 km/h
<h3>Principles of relative speed</h3>
The time elapsed when the cars are close to each other is calculated by applying the principles of relative speed.
Thus, the time elapsed when the vehicles are closest to each other is 20 min.
