Let 'm' denotes the mass of helicopter, 'g' denotes the gravity and 'a' denotes the acceleration.
We know that
Put
So,
Also, as per Newton's second law,
Put
So,
We know that the lift force is the sum of the gravitational force and the force of motion.
Answer:
v = 0.416 m/s
Step-by-step explanation:
Give that,
Distance covered by a train, d = 50 m
Time taken, t = 120 s
We need to find the speed of a train. The formula for speed of an object is equal to the total distance covered divided by total time taken. It can be given by :
So, the speed of a train is 0.416 m/s.
