Explanation / Answer

(a)

HMax =u2sin2A/2g

HMax =37.82sin244.5/19.62

HMax =35.77 m

HMax =35.8 m

(b)

T = 2usinA/g

T = 2*37.8*sin44.5/9.8

T = 5.4 s

(c)

R = u2sin2A/g

R = 37.82sin89/9.81

R = 145.62 m

R = 145 m

(d)

u = 37.8 m/s

A = 44.5 degree
t = 1.6

horizontal motion,
vh = 37.8 cos 44.5

vh= 26.96 m/s
vertical motion,
v = u + at
vv = 37.8*sin 44.5 - 9.8*1.6

vv= 10.8 m/s

v = sqrt[ 272 + 10.82]
v = 29.1 m/s
