Can anyone help me with this problem? Thank-you(adsbygoogle = window.adsbygoogle || []).push({});

A 87 kg pole-vaulter falls from rest from a height of 6.8 m onto a foam-rubber pad. The pole-vaulter comes to rest 0.30 s after landing on the pad.

(a) Calculate the athlete's velocity just before reaching the pad ( in m/s downward).

(b) Calculate the constant force exerted on the pole-vaulter due to the collision (in N upward).

Would you incorporate kinematics in here or not? {x=1/2(vi+vf)t}
