amplitude is kept at 4.0 cm and the vibration
frequency increased to 50 Hz. T
The particle passes through the origin at time t = 0.0 s, travelling in the +y-direction.
(i) At what time does the valve first pass through the position y = 3.0 cm?
(ii) What is the speed at this point?
(iii) What is the acceleration at this point?
(iv) At what positions will the valve have a speed of 6.0ms−1?
The Attempt at a Solution
= 2*50*pi= 100pi
= 100pi*4= 400pi
dont know if this is correct?
also dont know how to get the time and postions part (i and iv)
