Academics

A 50 g mass is attached to a massless spring and allowed to oscillate around an equilibrium according to: y(t) = 1.2*sin( 3.1415*t ) where y is measured in meters and t in seconds

1) What is the spring constant in N/m? k = N/m

2) What is the Total Energy in the mass and spring in J? E = J

3) What is the maximum Kinetic Energy of the mass? KE = J

4) What is the maximum velocity of the mass in m/s ? v(max) = m/s
