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

29.36
`m/s` downwards

Step-by-step 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
