Explanation / Answer

Solution:

Let us go to the basics first.

You need to work out the horizontal and vertical components.
Horizontally, Vx = d / t = 3m / 1.3s = 2.307 m/s
Vertically, s = So + Vv*t + ½at²
0 = 4 + Vv*1.3 - ½ * 9.8m/s² * (1.3)² = Vv*1.3 - 4.281
Vv = 4.281 / 1.3 = 3.293 m/s

c) max height = 4 + Vv2/ 2g = 4 + (3.293)2 / 2*9.8 = 4.55 m (Answer c)

d) At impact, vertical v = Vv + at = 3.293 - 9.8*1.3 = -9.447 m/s
so mag V = (9.4472 + 2.3072) m/s = 9.724 m/s (Answer d)

Thanks!!!
