Answer:
The final speed of the railroad car
V= 1.14
Explanation:
That's the final speed of the both railroad car
The ball takes about 1.15 seconds to reach the wall
<h3>Further explanation</h3>Acceleration is rate of change of velocity.
<em>a = acceleration ( m/s² )</em>
<em>v = final velocity ( m/s )</em>
<em>u = initial velocity ( m/s )</em>
<em>t = time taken ( s )</em>
<em>d = distance ( m )</em>
Let us now tackle the problem!
This problem is about Projectile Motion
<u>Given:</u>
initial speed = u = 25 m/s
angle of speed = θ = 40.0°
horizontal distance = x = 22.0 m
<u>Unknown:</u>
time taken by the ball = t = ?
<u>Solution:</u>
<em>We will use this following formula to find the time taken by the ball to reach the wall:</em>
The ball takes about 1.15 seconds to reach the wall
