how would i find acceleration if a squash ball is traveling at 9m/sec horizontally to the right and is stopped by a racket in 0.003 secs?
Acceleration is the rate of change of an object's velocity over time. It is a vector quantity, which means it has both magnitude and direction.
The formula for acceleration is a = (vf - vi) / t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time. It is typically measured in meters per second squared (m/s^2).
Average acceleration is calculated over a period of time, while instantaneous acceleration is calculated at a specific moment in time. Average acceleration takes into account the initial and final velocities, while instantaneous acceleration only considers the velocity at a single point in time.
The mass of the ball does not directly affect its acceleration. According to Newton's Second Law of Motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This means that a ball with a larger mass will require a greater force to accelerate it at the same rate as a ball with a smaller mass.
The acceleration of a ball can be affected by external forces such as friction, air resistance, and gravity. The surface on which the ball is rolling or bouncing can also affect its acceleration. Additionally, the initial velocity and direction of the ball can impact its acceleration as well.
