Question

A soccer ball has a mass of 0.400 kg. what is the magnitude of the weight of the ball?

Answer 1

3.92 N

The weight of an object is equal to its mass multiplied by the acceleration due to gravity.

On Earth, the acceleration due to gravity is approximately 9.8 m/s^2.

Therefore, the weight of a 0.400 kg soccer ball would be:

Weight = (0.400 kg) * (9.8 m/s^2) = 3.92 N (Newton)

Answer 2

Answer:
Impulse = 18.53 kg m / s
Net force = 1853N
Step-by-step explanation:
Mass of the ball, m = 0.4 kg
Initial velocity = 20 m/s horizontally left
Final velocity = 30 m/s at 45 degrees from horizontal
Time of collision = 0.010 s
