Ablock of unknown mass is attached to a spring with a force constant of 6.50 n/m and undergoes simple harmonic motion with an amplitude of 10.0 cm. when the block is halfway between its equilibrium position and the end point, its speed is measured to be 30 cm/s. calculate a) the mass of the block, b) the period of the motion, and c) the maximum acceleration of the block.

Thomas his older brothers, who own a junk yard, on the weekends to earn extra money. he likes to them push broken-down cars to the back of the junk yard because it makes him feel strong. last saturday, they pushed three cars with different weights, and he noticed he used different amounts of force for each one. the cars were the following weights: white car: 2,700 kg red car: 1,500 kg blue car: 2,100 kg think about how much force is needed to move each car. which correctly lists the cars in order from the most to least amount of force needed to move them? a) white, blue, red b) blue, red, white c) red, white, blue d) white, red, blue
