Question

A net force of 66 newtons accelerates a child at 2.0 m/s? down a smooth playground slide. What is the mass of the
child?

A 130 kg
B68 kg
© 64 kg
D 33 kg

Answer 1

Answer:The answer is D 33

Explanation:

Answer 2

The mass of the child accelerating at 2 m/s² by a net force of 66 N is 33 Kg (Option D)

Relationship between force and acceleration

Force is related to acceleration according to the following equation

Force (F) = mass (m) × acceleration (a)

F = ma

With the above formula, we can obtain the mass of the child

How to determine the mass of the child

• Acceleration (a) = 2 m/s²
• Force (F) = 66 N

• Mass (m) =?

F = ma

66 = m × 2

Divide both side by 2

m = 66 / 2

m = 33 Kg

Thus, the mass of the child is 33 Kg
