Plzz solve 3rd ques with explaination 15pts

Answer 1

Solution :

⏭ Given:

✏ A force of 5N gives mass m1 an acceleration of 8m/$s^2$ and a mass m2 an acceleration of 24m/$s^2$.

⏭ To Find:

✏ Acceleration prodeced in joint mass by same force.

⏭ Concept & Formula:

✏ This question is completely based on concept of newton's second law of motion.

✏ Formula of force in terms of mass and acceleration is given by...

• F = m × a

⏭ Terms indication:

• F denotes applied force
• m denotes mass of object
• a denotes acceleration

⏭ Calculation:

_________________________________

1) First case:

✏ F = m1 × a1

✏ 5 = m1 × 8

✏ m1 = 5/8

✏ m1 = 0.62kg

_________________________________

2) Second case:

✏ F = m2 × a2

✏ 5 = m2 × 24

✏ m2 = 24/5

✏ m2 = 0.21kg

_________________________________

3) Third case:

↪ Joint mass m3 = m1 + m2 = 0.83kg

✏ F = m3 × a3

✏ 5 = 0.83 × a3

✏ a3 = 5/0.83

✏ a3 = 6m/$\bold{s^2}$

_________________________________

⏭ Additional information:

• Force and acceleration are vector quantities.
• Mass is scalar quantity.
• Vector quantity has both magnitude as well as diretion.
