The final velocity of the ball is  20.8 m/s. Option C

What is the final speed?

Now we have the equation;

v^2 = u^2 + 2gh

v = final velocity

u = initial velocity

a = acceleration

s = distance

v^2 = (11.4)^2 + (2 * 10 * 15.5)

v^2 = 129.96 + 310

v = √ 129.96 + 310

v = 20.8 m/s

b)

Given that;

R = u^2sin2θ/g

Where;

g = acceleration due to gravity

θ = acute angle

u = velocity

R = (60)^2 sin2(30)/10

R = 310 m
