what is the maximum values of velocity, acceleration, kinetiv enegy, elastic pot

Question

what is the maximum values of velocity, acceleration, kinetiv enegy, elastic potential energy, respectively.

Calculate the numerical value for the total energy.

You have a block resting on a horizontal smooth surface. The block (mass m) is attached to a horizontal spring (spring constant k), which is fixed at one end. The spring can be compressed and stretched. The mass is pulled to one side then released. The maximum displacement is 15 cm. If k = 150 N/m, calculate the mass of the block. what is the maximum values of velocity, acceleration, kinetiv enegy, elastic potential energy, respectively. Calculate the numerical value for the total energy.

Explanation / Answer

F = kx = ma

m = kx/a = 22.5 / a

what is the maximum values of velocity, acceleration, kinetic enegy, elastic potential energy, respectively.

v = 2.25t/m = 1.5/?m

a = 2.25/m

Ke = 2.42 t2/ m2

PE =1/2 kx2 = 1.6875 J

total energy is always. 1.6875 J
