Solution) Mx > My > Mz
Fx = Fy = Fz = F
KE = (P^2)/(2M)
P is momentum
P = MV
F = Ma = M(V/t)
Ft = MV
Ft = P
Since force and time is same so momentum is same .
So KE = (P^2)/(2M)
KE is inversely proportional to mass
AS mass increases KE decreases
Since car X has greatest mass it has least kinetic energy
Car Z has least mass so it has greatest kinetic energy.
There car Z has most amount of kinetic energy.
Option(d)
Three cars, car X, car Y, and car Z, begin accelerating from rest at the same time. Car X is more massive than car Y, which is more massive than car Z. the net accelerating force exerted on each car is identical. After 10 seconds, which car has the most amount of kinetic energy? I understand all the cars have the same amount of momentum, but I'm not sure about the kinetic energy. Please help!

1. During World War I, Germany used a "Big Bertha" cannon to hurl shells into Paris 30 miles away. This gun also had a long barrel. What is the reason for using a long barrel in these guns? 2. Consider two less-than-desirable options. In the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. In the second option you are driving 30 mph and crash head-on into a stationary brick wall. In...
