Final answer:
The student's question involves physics calculations related to the motion and forces when lifting a whale shark with a crane. By applying Newton's second law of motion and the equations of motion for acceleration and force, the acceleration can be determined followed by the net force required.
Step-by-step explanation:
The subject question involves calculating the acceleration and the forces involved when a crane lifts a whale shark. The shark has a mass of 2.00 x 10⁴kg, equivalent to the mass of three average adult elephants, and it is accelerated from rest to a speed of 1.0 m/s over an interval of 2.5 seconds. The physics concepts applicable here include Newton's second law of motion and the equations of motion, specifically dealing with acceleration and force. To find the acceleration, use the formula: acceleration (a) = change in velocity (Δv) / time (t). Given that the final velocity is 1.0 m/s, the initial velocity is 0 m/s (since it's from rest), and the time is 2.5s, the acceleration a can be calculated. After finding the acceleration, the net force applied by the crane can be calculated using Newton's second law, F = ma, where m is the mass and a is the acceleration. This physics problem corresponds to the motion of objects and forces, which is a common topic covered in high school physics courses.
