A receiver on a football team runs 8.0 m [E] and then turns abruptly to run 12.0 m [W]. If the entire motion takes 5.0 s, determine the receiver's: (a) total distance travelled. (b) total displacement. (b) average speed. (c) average velocity.

The position, x, of a longboarder as a function of time, t, is given by x = (-3.22 m/s)t + (7.0 m) At a time of 5.6 s, what is the displacement of the longboarder from the initial position?

1) What is the displacement of an object dropped from a height after 1.50 seconds? 2) How long will it take a dropped object to reach the ground if dropped from a height of 1.75 meters? 3) An object is flipped upward at a velocity of 30.0 m/s. At what point in its ascent will its velocity be 2.0 m/s? 4) How long will a coin launched upward at a velocity of 25.0 m/s attain a velocity of 15.0 m/s? 5) A 5-kg rock is dropped from a height of 15.0 m. a) What will be its velocity 0.75 seconds after its drop? b) What will be its velocity at a point 8.0 m from the ground? 6) How high will an object launched upward travel if its initial velocity was 15.0 m/s?

A hovercraft has an initial position of r(t = 0s) = 235m @ 265◦, an initial velocity of⃗v(t = 0s) = 125m/s @ 14◦, and a constant acceleration of ⃗a = 21.3m/s^2 @ 143◦.(a) How long does it take for the x coordinate of the hovercraft’s position to reach -100m?(b) What is the hovercraft’s position at this time?(c) What is the hovercraft’s velocity at this time?
