Answer:
The time taken is
Explanation:
From the question we are told that
The mass of the ball is
The time taken to make the first complete revolution is t= 3.60 s
The displacement of the first complete revolution is
Generally the displacement for one complete revolution is mathematically represented as
Now given that the stone started from rest
Now the displacement for two complete revolution is
Generally the displacement for two complete revolution is mathematically represented as
=>
=>
So
The time taken to complete the next oscillation is mathematically evaluated as
substituting values
Answer:
a)
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
a = Acceleration
The acceleration of the bicycle and rider is -1.5 m/s²
Force
The magnitude of the average force needed to bring the bicycle and its rider to a stop is
