Question

a 100g apple is falling from a tree. what is the impulse that earth exerts on it during the first 0.50 s of its fall

Answer 1

0.49N*s

Step-by-step explanation:

First we need to calculate the velocity using the formula [ v = at ].

v = 9.8 * 0.50

v = 4.9m/s

Convert 100g to kg.

100 / 1000 = 0.1kg

Now we can calculate the momentum using the formula [ p = mv ].

p = 0.1 * 4.9

p = 0.49N*s

Best of Luck!
