A lion has a mass of 45 kg. Answer the following questions about it, using correct units. a. The lion runs at a speed of 14.2 m/
Eva8 [605]
A) The kinetic energy of an object is given by:
K= \frac{1}{2}mv^2
where m is the mass of the object, and v its speed. For the lion in our problem, m=45 kg and v=14.2 m/s, so its kinetic energy is
K= \frac{1}{2}mv^2= \frac{1}{2}(45 kg)(14.2 m/s)^2=4537 J

b) the increase in gravitational potential energy of the lion is given by:
\Delta U = mg \Delta h
where g is the gravitational acceleration, and \Delta h is the increase in altitude of the lion. In this problem, \Delta h=28 m, so the increase in gravitational potential energy is
\Delta U=mg \Delta h=(45 kg)(9.81 m/s^2)(28 m)=12361 J

c) When the fox reaches the top of the tree, its gravitational potential energy is
U=mgh=(1.8 kg)(9.81 m/s^2)(3.8 m)=67 J
As it jumps, its kinetic energy is
K= \frac{1}{2}mv^2= \frac{1}{2}(1.8 kg)(8.1 m/s)^2=59 J
So the total mechanical energy of the fox as it jumps is
E=U+K=67 J + 59 J =126 J
