Question

from the point directly beneath you at a constant velocity of 𝑣𝑓=2.50 m/s . You want to calculate the time it takes for the ball to reach your friend. To do this, you can use the following equation: 𝑡=𝑑𝑥/𝑣𝑥 where 𝑡 is the time, 𝑑𝑥 is the horizontal distance, and 𝑣𝑥 is the horizontal velocity. First, let's find the horizontal distance 𝑑𝑥 . We can use the equation: 𝑑𝑥=𝑣0cos(𝜃)𝑡 where 𝑣0 is the initial velocity and 𝜃 is the angle above the horizontal. Substituting the given values, we have: 𝑑𝑥=8.60cos(34.0∘)𝑡 Next, let's find the horizontal velocity 𝑣𝑥 . We can use the equation: 𝑣𝑥=𝑣0cos(𝜃) Substituting the given values, we have: 𝑣𝑥=8.60cos(34.0∘) Now, we can substitute the values of 𝑑𝑥 and 𝑣𝑥 into the equation for time: 𝑡=(8.60cos(34.0∘)𝑡)/(8.60cos(34.0∘)) Simplifying the equation, we have: 𝑡=𝑡 Therefore, the time it takes for the ball to reach your friend is equal to the time it takes for the ball to reach your friend.

You want to calculate the time it takes for the ball to reach your friend. To do this, you can use the following equation:

𝑡=𝑑𝑥/𝑣𝑥

where  𝑡  is the time,  𝑑𝑥  is the horizontal distance, and  𝑣𝑥  is the horizontal velocity.

First, let's find the horizontal distance  𝑑𝑥 . We can use the equation:

𝑑𝑥=𝑣0cos(𝜃)𝑡

where  𝑣0  is the initial velocity and  𝜃  is the angle above the horizontal.

Substituting the given values, we have:

𝑑𝑥=8.60cos(34.0∘)𝑡

Next, let's find the horizontal velocity  𝑣𝑥 . We can use the equation:

𝑣𝑥=𝑣0cos(𝜃)

Substituting the given values, we have:

𝑣𝑥=8.60cos(34.0∘)

Now, we can substitute the values of  𝑑𝑥  and  𝑣𝑥  into the equation for time:

𝑡=(8.60cos(34.0∘)𝑡)/(8.60cos(34.0∘))

Simplifying the equation, we have:

𝑡=𝑡

Therefore, the time it takes for the ball to reach your friend is equal to the time it takes for the ball to reach your friend.
