Question

The average batter exerts a 7000 N force when hitting a baseball. Knowing this, how quickly does the 0.5 kg baseball accelerate?

a)14,000m/s²

b)7,000m/s²

c)3,500m/s²

d)1,400m/s²

Answer 1

The 0.5 kg baseball accelerates at a rate of 14,000 m/s² when hit by a force of 7000 N, according to Newton's second law of motion.

Step-by-step explanation:

To calculate how quickly the 0.5 kg baseball accelerates when hit by a 7000 N force, we use Newton's second law of motion, which states that acceleration (a) is equal to the force (F) divided by the mass (m). The formula for this is a = F/m.

Using the given values:

• F = 7000 N
• m = 0.5 kg

Substitute these values into the formula:

a = 7000 N / 0.5 kg = 14,000 m/s²

The correct answer is (a) 14,000 m/s².
