A rat was thrown at an angle of 37° with a speed of 10 m/s. How long is it in the air?

Question

agent0smith · Answer

Just...why was a rat thrown? What a bizarre scenario.

If this is a physics question, you can use equations of motion to solve it.

First find the y component of velocity, which is 10sin37.

Then use $$\Large v_f = v_0 + at$$ since you can solve for when the velocity is zero. Don't forget to double it, since when v reaches zero, it's only halfway through it's flight.

t = 1.2 s.

$$0 = 0 + v_{z0}t - \frac{ 1 }{ 2 }g t^2$$
$$t = \frac{ 2v_{z0} }{ g } = 2(10m/s) \sin 37°/ (9.8 m/s^2)$$

Seriously who the hell throws a rat? Was it alive?

jojokiw3 · Answer

:D YES.

agent0smith · Answer

Maybe it was thrown to kill it then.

jojokiw3 · Answer

Not only does it rid the world of a possible vermin, it also teaches physics. I'd say the rat lived a valuable life.

agent0smith · Answer

Agreed.

You're welcome. The main reason I even clicked on it was because I thought it said "A rat was thrown at a wall at an angle of..."
