1.) A golf ball is struck with a five iron on level ground. It lands 105.0m away 3.80 s later. What is the magnitude and the direction of the initial velocity?(Neglect air resistance.)

This is what I have for this problem: V=105/3.8 = 27.63m/s

Then I used y = Vyot - (1/2)g t^2 the answer from this was 70.76 for which I then used 70.76 sin 27.63 to get an angle.

thanks in advance for the help
