Question

I shoot a water balloon catapult at the end of the year rally with a velocity of
57m/s at 31 degrees. What velocity does it hit the ground with?

Answer 1

Answer:

29.36 $m/s$ downwards

Explanation:

Use the equation $v^{2} =u^{2} +2as$

Choose upwards as positive

v=?

u= 57sin31 (vertical component of initial velocity)

a= -9.8

s=0

$v^{2} = (57sin31)^2 +2(-9.8)(0)$

v=29.36 $m/s$ downwards
