Ball Thrown Upward: Motion Analysis and Calculations
Question: A player throws a ball upwards with an initial speed of 29.4 ms-1 . Solution: Upward direction: Position-Positive Velocity-negative Acceleration-positive Downward direction: Position-positive velocity – positive Acceleration-positive $${u=gt}$$ $${t=\frac {u}{g}}$$ $${t=\frac{29.4}{9.8}}$$ $${t= 3\sec}$$ Total time taken =Time taken to reach top +Time taken to reach the bottom $${3 \ s +3 \ s =6…
