Problem 1: One end of a spring with a spring constant of 159 N/m is held firmly in place, and the other end is attached to a block with a mass of 2.13 kg. The block undergoes SHO (simple harmonic motion) with no friction. At time t = 0.1818 s, the position and velocity of the block are x(0.1818 s) -0.08836 m v(0.1818 s) = 0.9604 m/s Part (a) What was the position, in meters, at t= 0.00 s? x(0.00 s)=1 m Part (b) What was the velocity, in meters per second, at t= 0.00 s?

so b= 6.09 s^-2  but you used 5.21. when I plug in the answers its wrong, can you please fix this.

PLEASE CONSIDER THE TOLERANCE. DONT GIVE ME SCIENTIFIC NOTATIONS

A good-quality measuring tape can be off by 0.58 cm over a distance of 23 m.What is its percent uncertainty?

A scanning electron micrograph of xylem vessels in a corn root shows the vessels magnified by a factor of 608. In the micrograph the xylem vessel is 5.60 cm in diameter. What is the diameter of the vessel itself, answer in cm? and By what factor has the cross-sectional area of the vessel been increased in the micrograph?

Pls consider the given significant digit

The tolerance is ± 1 in the 3rd significant digit.

I need the answer to 3 significant figures

Low percent error implies that measurements are closely grouped. is this true or false?

What, roughly, is the percent uncertainty in the volume of a spherical beach ball of radius r = 0.8460.04 m?
