Class 11 Physics Motion in a Plane Lecture 4

There will be obstacles. There will be doubters. There will be mistakes. But with hard work, there are no limits. – Michael Phelps

01:02:59 Example 4.9 A cricket ball is thrown at a speed of 28 m/s in a direction 30° above the horizontal. Calculate (a) the maximum height, (b) the time taken by the ball to return to the same level, and (c) the distance from the thrower to the point where the ball returns to the same level.
