How much force in Newtons is required to accelerate a 5 kg bowling ball at 2 m/s^2

Question

Responses:

2.5 N

7 N

3 N

10 N

Answer 1

To find the force required to accelerate an object, you can use Newton's second law of motion, which states:

\[ F = ma \]

where \( F \) is the force in Newtons, \( m \) is the mass in kilograms, and \( a \) is the acceleration in meters per second squared.

In this case:

• \( m = 5 , \text{kg} \)
• \( a = 2 , \text{m/s}^2 \)

Substituting the values into the equation:

\[ F = 5 , \text{kg} \times 2 , \text{m/s}^2 = 10 , \text{N} \]

Therefore, the force required is 10 N.

Answer 2

Which statement correctly applies to a car that changes its velocity over a period of time
Responses:

Forces are acting on it.

No net force is acting on it.

A nonzero net force is acting on it

The combination of all forces acting on it is zero.

Answer 3

The correct statement that applies to a car that changes its velocity over a period of time is:

A nonzero net force is acting on it.

This is because a change in velocity indicates that the car is accelerating (either speeding up, slowing down, or changing direction), which, according to Newton's second law of motion, requires a net force to be acting on the car.
