Question 1:
A 0.1 kg block attached to a spring of force constant 16.9 N/m oscillates with an amplitude of 6 cm. Find the maximum speed of the block. Answer in units of m/s.
Question 2:
Find the speed of the block when it is 3 cm from the equilibrium position. Answer in units of m/s.
Question 3:
Find its acceleration at 3 cm from the equilibrium position.
Answer in units of m/s2.1) Vmax = .06(16.9/.1)^.5
= 0.78 THIS IS CORRECT
2) v = Vmaxsin(pi/3)
= 0.78(pi/3)
= THIS IS WORONG
3) a = .5Vmaxomega
= .5(7.8) (16.9/.1)^.5
= THIS IS WRONG TOO
I tried and I got 2 and 3 wrong :( I ran out of solutions. help please
I was pretty sure one was right.. but it said it was wrong when I entered it :(
