Question

a) A 100-g apple is falling from a tree. What is the impulse that Earth exerts on it during the first 0.50 s of its fall? The next 0.50 s?
b) The same 100-g apple is falling from the tree. What is the impulse that Earth exerts on it during the first 0.50 m of its fall? The next 0.50 m?

Earth exerts different impulses during the two time intervals in (a) and different impulses during the same distances traveled in (b).

Earth exerts the same impulse during the two time intervals in (a) and the same impulse during the same distances traveled in (b).

Earth exerts the same impulse during the two time intervals in (a) but different impulses during the same distances traveled in (b).

Earth exerts different impulses during the two time intervals in (a) but the same impulse during the same distances traveled in (b).

Answer 1

Option (C) is correct .

Impulse = force × time.

Impulse = mg×t.

For same time interval "t" Is same and force due to gravity is always same mg.so it remains same For Same time interval .

But due to acceleration body travels same distance in different time interval hence for same distance interval Impulse will be different .
