The beanbag that is thrown at an angle.....
Firstly, we need to consider velocity in the vertical direction. If we define u as the initial speed of both bean bags, then
a) the vertical velocity of the bean bag thrown straight up is
b) the vertical velocity of the bean bag thrown at an angle is
We know that acceleration is
We can now use following definition of acceleration :
At the maximum height, the final vertical velocity will be nil, so
So (b), the bean bag thrown at an angle , will have a shorter flight time and will hit the ground first
