+37099 First you will need to find time, 't' to reach the apex (high point) ....this is where the y component of velocity is ZERO.
y component = 18 sin 52 = 14.184 m/s
Now vf = vo + at vf = velocity final = 0 vo = velocity original (14.184 m/s from above)
0 = 14.184 + (-9.8)t
results in t= 1.4473 seconds
THEN yf = yo + vt + 1/2 at^2
? = 1 + 14.184 (1.4473) +(1/2)(-9.8)(1.4473)^2 = Max height= final 'y' = 11.26 m
