Part I
An object is through from the origin at an initial velocity of v0 and at an angle θ in relation to the horizon.
a. write out r->(t) for the object
b. find the velocity vector and acceleration vector for the object.
c. calculate the angle between the velocity vector and the
acceleration vector at any point in time t.
Part II
An object is moving upwards on a slope at initial velocity v0. There is friction between the object and the slope.
a. Calculate the amount of time it will take for the body to return to its initial position.
b. what is the ratio between the final velocity and the initial velocity?
