4-) To become airborne, a 2.0g grasshopper requires a takeoff speed of 2.7m/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 take-off? (b) Find the magnitude of the average net force exerted on the grasshopper by its hind legs during takeoff
3-) Murtaza is at the back seat in a convertible car that has a constant velocity of 9.5 m/s on a straight road. He decides to throw a ball up in the air and catches the projectile at the same location on the car but 16 m farther down the road.
(a) In the frame of reference of the car, at what angle does Murtaza throw
the ball? (b) What is the initial speed of the ball relative to the car?
