Answer 1

Answer #1

a) we know the formula

y=voy*t+1/2at²............1)

t=d/vox=22/19.15=1.15s

from the figure

vox=vo*cos40=25*cos40=19.15m/s

voy=vo*sin40=25*sin40=16.07m/s

so putting the values the in equation 1

y=16.07*1.15+1/2*9.8*1.15²=12m

so the answer is 12 m

b) we have already found out vox

vox=vo*cos40=25*cos40=19.15m/s

c) we have

voy=vo*sin40=25*sin40=16.07m/s

d) no it has not reached it highest point because the vertical component is still in positive so it hits the wall before reaching the highest point.
