Question

Frogs have impressive jumping abilities, capable of jumps covering a horizontal distance of up to 30 times their body length.
a) If a frog jumps a distance of 60 cm on a flat surface (at a take-off angle of 45°)
then what is its take-off speed v = √vox+vy? The jump took a time of 0.3 s. What is the max height above ground ? Neglect air resistance. 
b) Why is the max height of the jump different from its horiz. distance, even though the take-off angle is 45° ? Explain.
c) During its jump, is the frog in free fall or not? Explain.
