Answer :
Final answer:
To calculate the work needed to set the movement of the motorbike and its rider at 15 m/s, we can use the formula Work = Change in Kinetic Energy. Using the given values, the work is calculated to be 112,500 J.
Explanation:
To calculate the work needed to set the movement of the motorbike and its rider at 15 m/s, we need to use the formula:
Work = Change in Kinetic Energy
Since the motorbike and rider have a combined mass of 150 kg and are initially at rest, the initial kinetic energy is zero. The final kinetic energy is given by:
Final Kinetic Energy = 0.5 * (mass) * (final velocity)^2
Substituting the given values, we have:
Final Kinetic Energy = 0.5 * 150 kg * (15 m/s)^2 = 112,500 J
Therefore, the work needed to set the movement of the motorbike and rider at 15 m/s is 112,500 Joules.
