Answer:
60 Newtons
Step-by-step explanation:
To calculate the force needed to accelerate a 20 kg ball object at 3 cm/5² (which should actually be 3 m/s²), we can use the formula force = mass x acceleration.
Using this formula, the force required can be calculated as follows: Force = mass x acceleration Force = 20 kg x 3 m/s² Force = 60 N.
Therefore, the force needed to accelerate a 20 kg ball object at 3 m/s² is 60 Newtons.
