Ok, this is the exact copy of the question-

"A stone is catapulted at time t = 0, with an initial velocity of magnitude 21.4 m/s and at an angle of 39.2° above the horizontal. What are the magnitudes of the (a) horizontal and (b) vertical components of its displacement from the catapult site at t = 1.00 s? Repeat for the (c) horizontal and (d) vertical components at t = 1.76 s."

Basically, it's asking

(a) What the change in x is at 1s
(b) What the change in y is at 1s
(c) What the change in x is at 1.76s
(d) What the change in y is at 1.76s

So respectively I got my answers as...

(a) 18.68m
(b) 10.33m
(c) 32.88m
(d) 11.62m

Is this correct?

Aw fuck...I wrote the original magnitude wrong in my book...goddamit...
