Question

A puma leaps from one cliff ledge to another, the second ledge leapt to is 0.7m higher than the first, as well as 2.4m further along the cliff.

1) Calculate the velocity with which the puma must take off in order to barely reach the second ledge.

2) If the puma weighs 50kg, calculate the impulse that the puma exerts on the first ledge in order to make this jump.

3) If the maximum force exerted by any one of the puma legs is 60N, calculate the minimum time which the puma's feet must spend in contact with the first ledge.

*Please answer this to the best of your ability, I'm so confused on how to find the velocity when only distance is given
