Projectiles launched at an angle

in 1989 during overtime in a high school basketball game in erir, pennsylvania, chris eddy threw a basketball a distance of 27.5 m to score and win the game. if the shot was made at a 50° angle and reached a height of 9ft above the horizontal, what was the initial speed of the ball, the total time spend in the air, and the speed at which the ball was launched?

unlike poles attract

see earlier answer

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
