Part B

What is its horizontal speed?

Express your answer to two significant figures and include the appropriate units.

vx =

a)let it's takeopp speed be v.so,

maximum height reached = v^2(sin^2(x))/(2*g)

or 11=v^2*sin^2(18)/(2*g)

or 11=v^2*0.095/(2*9.81)

or v=48 m/s

b) vx=47.663 cos(18)

=45 m/s
