Homework Statement
Part 1:
A 0.1 kg block attached to a spring of force constant 17.2 N/m oscillates with an amplitude of 16 cm. Find the the maximum speed of the block.
I solved this part using the equations for angular frequency and max velocity.
Part 2:
Find speed of the block when it is 8 cm from the equilibrium position. Answer in m/s.
Part 3:
Find acceleration in the same situation ^
Part 4:
Find the time it takes the block to move from amplitude 0cm, to amplitude 8 cm.
Homework Equations
ω = [itex]\sqrt{}k/m[/itex]
Vm = Aω
V(t) = -AωSin(ωt)
a(t) = - Aω^2Cos(ωt)
The Attempt at a Solution
Part 1 i figured out:
ω = [itex]\sqrt{}17.2/0.1[/itex] = 13.1149 rads
Vm = (.16)(13.1149) = 2.09838 m/s
For part 2 i tried using the equation for velocity as a function of time. But I'm not sure how to solve the equation without the value for time. So far i have:
V(t) = -(0.08)(13.1149)Sin(13.1149(t))
Thank you everybody
