Answer:
Mass of the ball is 2.07 kg
Step-by-step explanation:
Given that,
Acceleration of the car is +6.55 m/s^2
Force applied to the ball, F = 13.5 N
To find :
The mass of the ball.
Solve :
Let m is the mass of the ball. The force by an object is given by the product of mass and its acceleration. Its formula is given by:



m = 2.07 kg
Therefore, the mass of the ball is 2.07 kg.
