Need help with this urgently please!

1. Spring and mass system a) (10 pts) You have a spring of length 50 em and a block of mass 150 grams. When you hang the block from the spring you measured the length of the spring to be 52.5 cm. Then you pull the block down by 4.5 cm and release to set it in oscillation and measure the time period, T, using a stopwatch. What value of T would you expect from your measurement? bodno b) (5 pts) You take the same spring and hang a different block of mass 600 grams. What would be time period of the oscillating spring mass system with this block? bion Como c) (5 pts) what is the velocity, acceleration and total energy of the block when it is at the lowest point of the oscillation.

Answer 1

When the block is in equilibrium ang arx er en (0:1stg) (10) k = mg (2.545 m) k = 60 N/m Spring Constant. Time period of oselllation, T: 211 0.15kg T 0.314 Seconds b) 0.6 60 T = 0.635 c) Amplitude of oscillation, A = 45cm = 4.5 200²m Velocity at its lowest position (extmeste position is dono. Acceleration, a - Aw' = A() = (4.5*10*) (**) @=4.5 m/s2 Total energy, E = £ ma'w? = { (0-1)(0-5164(e) E = 6.1 Joules
