Answer:
at the highest point of the path the acceleration of ball is same as acceleration due to gravity
Explanation:
At the highest point of the path of the ball the speed of the ball becomes zero as the acceleration due to gravity will decelerate the motion of ball due to which the speed of ball will keep on decreasing and finally it comes to rest
So here we will say that at the highest point of the path the speed of the ball comes to zero
now by the force diagram we can say that net force on the ball due to gravity is given by
now the acceleration of ball is given as
so at the highest point of the path the acceleration of ball is same as acceleration due to gravity
Answer:
v = 0.5 m/s
f = 0.42 Hz
ω = 2.6 rad/sec
Explanation:
- By definition, the translational speed is the rate of change of the position with respect to time.
- The change in position along a complete revolution is just the following:
- Δs = 2*π*r = 2*π*0.19 m = 1.19 m
- The time needed to complete a revolution is 2.4 s, so the translational speed can be written as follows:
- The frequency in Hz is just the inverse of the time needed to complete a revolution (known as the period T), as follows:
- f = 1/T = 1/2.4s = 0.42 Hz (2)
- Finally, the angular speed is the rate of change of the angle rotated with respect to time, as follows:
