Question

Free fall question

Answer 1

If a baseball is thrown horizontally and golf ball and a soccer ball are simply dropped at the same time. Which ball will hit the ground first?

Answer 2

@UnkleRhaukus

Answer 3

at what rate are they objects accelerating ?

Answer 4

Are they all starting from the same hight initially?

Answer 5

-9.81 m/s2 no air resistance

Answer 6

yes same height

Answer 7

Would they all fall at the same time?

Answer 8

yes

Answer 9

Could you give your reasoning?

Answer 10

try it out at home, drop two object of the same shape (spheres ) from rest , from the same height, they should land at the same time, even if one has horizontally velocity


they land at the same time because the are both accelerating with the same acceleration (gravity ),

Answer 11

the initial vertical velocity of the baseball would be 0? and the initial velocities of the other two balls will also be 0 since they are free falls. Is this accurate?

Answer 12

The question states that
the golf ball and a soccer ball are 'simply dropped'
=> they start with zero velocity

the baseball is thrown horizontally
=> the vertical velocity starts as zero

Answer 13

yes that is what I meant

Answer 14

The equation you could use is
\[y(t) = y_0+{v_y}_0t+\tfrac12a_yt^2\]

Where the \(y_0\)'s are equal , and the \(v_y\)'s are zero, the \(a_y\)'s are \(-g\)
