Question

Use the approximation that v avgPflm for each time step A block of mass 0.49 kg is placed at rest on a relaxed vertical spring-like device of length 0.20 m which exerts an upward force of Fy2.1 x 10, where s is the stretch. With a time step of 0.04 s, calculate the length L of the device and the y component of the velocity of the block at t 0.04 s. (For Vy indicate the direction with the sign of your answer.) m/s with a time step of 0.04 s, calculate the length L of the device and they component of the velocity of the block at t =0.08 s. (For V indicate the direction with the sign of your answer.)

Explanation / Answer

For first case

L = 0.2004 m

Vy = 70.24 m/ sec

For second case

L = 0.2160

Vy = 35.11 m/sec
