Q.18
What combination of values will result in a spring - block system with the greatest frequency?
A = 50 cm; k = 80 N/m; m = 2 kg
A = 50 cm; k = 100 N/m; m = 2 kg
A = 50 cm; k = 100 N/m; m = 4 kg
A = 75 cm; k = 80 N/m; m = 2kg
A = 75 cm; k = 100 N/m; m = 4 kg
Q.19
A block of mass m = 4 kg on a frictionless, horizontal table is attached to one end of a spring of force constant k =N/m and undergoes simple harmonic oscillations about its equilibrium position (x =with amplitude A = 6 cm. If the block is at x = 6 cm at time t =then which of the following equations (with x in centimeters and t in seconds) gives the block's position as a function of time?
x = 6 sin(10t + 0.5π)
x = 6 sin(10πt + 0.5π)
