Does it mean as much as you thought it would ?
Answer:
force of 279 N
53.75 degrees from east to north
Explanation:
let net force be F , Fn - north force , Fe - east force
let the direction be α angle from east to north
The coefficient of restitution is a measure of the interaction of the ball with the material of the ground. Since the ground is too solid to move (usually), or give way, the energy of the ball-ground system must be conserved in the main. Some of the energy is released as sound waves but the rest is given to, or reflected back to the ball and it follows the path of reflection. When the ball is dropped vertically it returns along the same path. So the force is actually the potential energy created by dropping converted to kinetic energy on collision with the ground. This is the origin of the force making it bounce.
Answer:
10 m/s²
Explanation:
Force is the product of mass of an object and its acceleration
The formula is : F= m*a -----where m is mass and a is acceleration
Use the values given in the equation as;
F= m*a
1000 = 100 * a
1000/100 = a
10 = a
10 m/s² = a
