The magnitude of vector a is 6.3 m. it points in a direction which makes an angle of 1459 measured counterclockwise from the positive x-axis. (a) what is the x component of the vector -3.5a? (b) what is the y component of the vector-3.5a? (c) what is the magnitude of the vector -3.5a?

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)

You will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. (refer to the walk-through video to locate the online lab within the online textbook).
