Equations with Question

The Batman is attempting to catch the Joker. The Joker stands on a platform near an exit and Batman is on the floor below. Knowing how fast Batman can move up to the platform the Joker uses a ploy to slow the Batman down allowing himself to escape.

Standing on the platform’s edge so that the Batman can see him, the Joker pulls out a 7.00kg baby in a 4.30kg basket, and yells to the Batman and the throws the baby and basket into the air with a speed of 7.00and an angle of 60.00degrees above the horizontal yelling “Congratulations it’sa bouncing baby boy...hopefully”.

The Batman who is standing 7.00m away from the platforms edge of course gives up the pursuit and races to catch the basket. The baby and basket are thrown initially at a height of 6.40m above the floor that the Batman in on. To make meters worse the baby basket is a spring loaded “Joker Basket”and when the Baby and basket at the maximum height the basket launches the baby out directed away from the platform.

Given the catching height of batman, and that the basket launch does not affect the time that the baby is in the air, how fast must Batman run to catch the baby at a height of 1.70m above the ground. Given that the basket when at that height is 3.30m from the platform.

If the speed you find is not humanly possible, it’s okay...this isthe Batman after all.IMPORTANT MATH RULES, for all trig functions and all but the last calculationround to 4 decimal places, your final answer must be rounded to 2 decimal places, and the acceleration due to gravity is 9.8 m/s2 down.
