The impulse is 10 kg m / s.
<u>Explanation:</u>
An impulsive force is a short duration of force. The result of the force acting for the given amount of time is that the object's speed up or slow down of mass. The impulse experienced equals the change in momentum of the object.
Given the mass m = 1.0 kg
The formula is given as,
Impulse = mass ( change in velocity)
= 1.0 ( 10 - 0)
Impulse = 10 kg m /s.
Answer:
b. Medicine balls
Explanation:
A medicine ball (also called an exercise ball, or a health ball) is a weighted ball about the shoulder diameter (approx. 13.7 inches), often used for recovery and strength training.... In 1705 similar large balls had been used in Persia.So you can use your medicine ball as a projectile to boost the strength of your throws.
Answer:
If you push horizontally with a small force, static friction establishes an equal and opposite force that keeps the book at rest. As you push harder, the static friction force increases to match the force. Eventually maximum static friction force is exceeded and the book moves.
