Question

If an object is moving at 150 m/s2 and it is pushed with 500 N, what is the mass of the object?

Answer 1

Answer:

M= f/a

so mass= 200N/500m/s^2

mass= 0.4kg or 400 grams

Answer 2

Understanding the question: This question says that an object is moving at an acceleration of 150 m/s² and it is pushed with force of 500 N, then we have to find out that what is the mass of the object? Let's solve this question!

Provided that:

• Acceleration = 150 m/s²
• Force = 500 Newton

To calculate:

• Mass of the object

Solution:

• Mass of the object = 3.33 kg

Using concept:

• Newton's second law of motion that is the formula of force

Using formula:

• F = ma

(Where, F denotes force, m denotes mass and a denotes acceleration)

Required solution:

→ F = ma

→ 500 = m(150)

→ 500 = m × 150

→ 500/150 = m

→ 50/15 = m

→ 10/3 = m

→ 3.33 = m

→ m = 3.33 kg

→ Mass of the object is 3.33 kg

Verification:

~ To verify our solution we have to put the value of acceleration and mass to find out the force, of we get 500N as force then our final result is absolutely correct!

→ F = ma

→ F = 3.33(150)

→ F = 499.50

→ F ≈ 500 N

→ Force = 500 Newton

Henceforth, verified!
