Question:

To become airborne, a 2.0-g grasshopper requires a takeoff speed of 2.7 m/s. It acquires this speed by extending its hind legs through a distance of 3.7 cm.

(a) What is the average acceleration of the grasshopper during takeoff?

(b) Find the magnitude of the average net force exerted on the grasshopper by its hind legs during takeoff.

(c) If the mass of the grasshopper increases, does the takeoff acceleration increase, decrease, or stay the same?

(d) If the mass of the grasshopper increases, does the required takeoff force increase, decrease, or stay the same? Explain.
