Question

Calculate the value of the force that a weightlifter makes when lifting 150 kg at 2 m/s and 3 m/s.

A) \( F = 300 N \) and \( F = 450 N \)

B) \( F = 600 N \) and \( F = 900 N \)

C) \( F = 150 N \) and \( F = 300 N \)

D) \( F = 450 N \) and \( F = 900 N \)

Answer 1

The force the weightlifter makes when lifting an object can be calculated using the formula F = m * a. For a mass of 150 kg lifted at 2 m/s, the force is 300 N. For a mass of 150 kg lifted at 3 m/s, the force is 450 N.

Step-by-step explanation:

To calculate the value of the force that a weightlifter makes when lifting an object, we can use the formula:

F = m * a

where F is the force, m is the mass, and a is the acceleration.

For the first scenario, when lifting 150 kg at 2 m/s, the force can be calculated as:

F = 150 kg * 2 m/s = 300 N

For the second scenario, when lifting the same mass at 3 m/s, the force can be calculated as:

F = 150 kg * 3 m/s = 450 N

Therefore, the correct answer is:

A) F = 300 N and F = 450 N
