We can find the average speed of the body by finding the total distance covered, and then dividing it by the total time of the motion.
The total distance covered is:
while the total time of the motion is
So, the average speed of the body is:
The total distance covered is:
while the total time of the motion is
So, the average speed of the body is:
Answer:
F= 224 N
Explanation:
Given that
mass ,m = 80 kg
Radius ,r= 5 m
speed at the top v= 8 m/s
The force at the top = F
Now by using the Second law of Newton's
Now by putting the values
Take g = 10 m/s²
F= 224 N
Therefore the force exerted by the track at the top position will be 224 N.
