A herder is herding his sheep into the corral. A mother sheep and its lamb are both running at 3.0 m/s towards the corral. The sheep has a mass of 60 kg and the lamb has a mass of 20 kg. a. What is the kinetic energy of the sheep. b. What is the kinetic energy of the lamb?
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.
right. Apparently you have a problem determining who you are with your screen name. It helps us to help you better if you stick to a single screen name.
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
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
To find the kinetic energy of an object, we use the formula:
Kinetic Energy = (1/2) * mass * velocity^2
a. To find the kinetic energy of the sheep, we use the given mass and velocity of the sheep. Plugging in the values:
Mass of the sheep (m) = 60 kg
Velocity of the sheep (v) = 3.0 m/s
Kinetic Energy of the sheep = (1/2) * 60 kg * (3.0 m/s)^2
= (1/2) * 60 kg * 9.0 m^2/s^2 [Squaring the velocity]
= 270 J [Joules]
Therefore, the kinetic energy of the sheep is 270 Joules.
b. Similarly, we can find the kinetic energy of the lamb using its mass and velocity. Plugging in the values:
Mass of the lamb (m) = 20 kg
Velocity of the lamb (v) = 3.0 m/s
Kinetic Energy of the lamb = (1/2) * 20 kg * (3.0 m/s)^2
= (1/2) * 20 kg * 9.0 m^2/s^2
= 90 J [Joules]
Thus, the kinetic energy of the lamb is 90 Joules.
