Answer:
His kinetic energy when he runs at that 5 m/s is 750 joules
Explanation:
The given information are;
The mass of, Lance, the runner = 60-kg
The speed by which Lance is running = 5 m/s
The kinetic energy, KE, is given by the relation;
KE = 1/2×m×v²
Where;
m = The mass = 60-kg
v = The instantaneous speed of motion = 5 m/s
The kinetic energy can be found by substituting the values of the variables in the kinetic energy equation as follows;
KE = 1/2 × 60 kg × (5 m/s)² = 750 joules
His kinetic energy when he runs at that 5 m/s is 750 joules.
The kinetic energy when he runs at that 5 m/s is 750 joules.
