KE = 1/2*m*v^2
That the answer to both question. If so can you explain to me to steps. for both? You just confused me more. there is 2 question a. & be
Yes, you want the KE for both and you use the same formula for both.
Confusing. You substitute the numbers and solve the equation.
KE = 1/2*m*v^2
For the first one you have
m = 60 kg
v = 3 m/s
KE = 1/2*60*(3)^2
KE = 30*9 = 270 joules
You do the second one the same way.

For part 2.
KE =1/2*mv^2
m= 20 kg
v= 3 m/2
KE= 1/2*20*(3)^2
KE=10*9=90 joules
KE =1/2*mv^2
m= 20 kg
v= 3 m/2
KE= 1/2*20*(3)^2
KE=10*9=90 joules
