A tennis rocket hits a sand - filled tennis ball with aforce of 4.5 N. While the 0.3 kg ball is in contact with the racket, wath is its acceleration
Yes
To find the acceleration of the ball, we need to use Newton's second law of motion, which states that the force acting on an object is equal to the product of its mass and acceleration. The formula can be written as:
F = m * a
Where:
F is the force acting on the object (in this case, the force applied by the racket),
m is the mass of the object (the tennis ball), and
a is the acceleration of the object.
In this case, the force applied by the racket is given as 4.5 N, and the mass of the ball is 0.3 kg. We can rearrange the formula to solve for acceleration:
a = F / m
Plugging in the given values:
a = 4.5 N / 0.3 kg
a ≈ 15 m/s²
Therefore, the acceleration of the ball while in contact with the racket is approximately 15 m/s².
