Its the floor pushing up on the player, this one is correct
Seriously this is fun dont know why u want me to enjoy this so ummmm hmmm lolololol the equation for this would be s=vif+1/2at^2 so time is lets see plug it and vell vi=0 since it started from rest so s=1/2at^2 and plug it in the displacement and time 110=1/2 a 5.21^2 and solve it and u get 8.1m/s^2
Kinetic energy is calculated by using formula:
Ek = 1/2*m*v^2
Now we replace values of mass and speed in this formula.
Ek = 1/2*10*3^2 = 45.0J
When you have a formula and all variable values are given in the text of question just replace variable values in equation and find the final value.
