Homework Statement
A plane traveling at a speed of 1300 km/h in a northernly direction at a height of 5 km above the the ground suddenly climbs at an angle of 45 degrees to to horizon. Maintaining the speed and angle it releases a projectile as it passes through 7 km in altitude. Find the...
If speed of sound=340 m/s then (16.5m)/(340m/s)=0.049s. Subtract that from 2.45s and it took the ball 2.401s to reach the pins and then 0.049s for the sound to return back to the person. Correct?
I've tried a few different equations but I'm not sure how to start this problem. I just realized I'm looking for the initial velocity since the speed of the ball is constant.
A bowling ball traveling with constant speed hits the pins at the end of a bowling lane 16.5 m long. The bowler hears...
