Answer :
The kinetic energy of a 150 kg bear running at 3 m/s would be 67.5 Joules.
What is mechanical energy?
Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total potential energy stored energy in the system which is represented by total potential energy
ME = KE + PE
As given in the problem we have to calculate the kinetic energy of a 150 kg bear running at 3 m/s
K.E =?
m = 150 kg
v = 3 m/s
The total kinetic energy is given by the formula
KE = 1/2mv²
By substituting the respective values in the formula of kinetic energy
K.E =?
m = 150 kg
v = 3 m/s
KE =1/2×150×3²
KE= 67.5
Thus, The kinetic energy of a 150 kg bear running at 3 m/s would be 67.5 Joules.
