- A ball is traveling in 2-d according to the following equations:
x(t) = (4 + 17t2
) m.
y(t) = (3 + 2t) m.

b. What is the speed of the ball and its direction at t=1 s.
c. Calculate the average acceleration of the ball between t=0 and t=1 s.
d. What is the acceleration of the ball at t=1s?
e. What is the magnitude and direction of the acceleration of the ball at t=1 s.
