Answer:
0.014s
Explanation:
Given parameters:
Mass of the ball = 0.058kg
Force = 260N
Velocity of the ball = 63m/s
Unknown:
Time of contact = ?
Solution:
To solve this problem, we apply Newton's second law of motion which is mathematically expressed as;
Ft = m(v - u)
F is the force
t is time
m is the mass
v is the final velocity
u is the initial velocity = 0m/s
Insert the parameters and find t;
260 x t = 0.058(63 - 0)
260t = 3.65
t = 0.014s
I believe the answer is true.
To give solution to the exercise we must use the concepts of Torque, Vector magnitude and vector direction of the forces.
For the given problem we have to
In this way the torque acting on the particle as a function of distance and time is,
The net torque acting on the particle is
PART B) The direction of the torque is given by,
Therefore the torque direction is 48.04° below the x axis.
Answer:
Explanation:
Unknown fork frequency is either
335 + 5.3 = 340.3 Hz
or
335 - 5.3 = 329.7 Hz
After we modify the known fork, the unknown fork frequency equation becomes either
(335 - x) + 8 = 340.3
(335 - x) = 332.3
x = 2.7 Hz
or
(335 - x) + 8 = 329.7
(335 - x) = 321.7
x = 13.3 Hz
IF the unknown fork frequency was 340.3 Hz,
THEN the 335 Hz fork was detuned to 335 - 2.7 = 332.3 Hz
IF the unknown fork frequency was 329.7 Hz,
THEN the 335 Hz fork was detuned to 335 - 13.3 = 321.7 Hz
