In general it is best to conceptualize vectors as arrows in space, and then to make calculations with them using their components. (you must first specify a coordinate system in order to find the components of each arrow.) this problem gives you some practice with the components. let vectors a =(2,−1,−2), b =(4,−3,0), and c =(−2,1,6). calculate the following, and express your answers as ordered triplets of values separated by commas.

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds

Which of the following statement is false

Asled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slidesa distance d1 down the slope and then covers the distance d2 alongthe horizontal terrain before stopping. find the coefficient ofkinetic friction μk between the sled and the ground, assumingthat it is constant throughout the trip. find the coefficient of kinetic frictionμk. express your answer in terms of someor all of the variables d1, d2, and θ.
