Here are the solutions to your questions.

1) A body of mass $4.5 \, \text{kg}$ moves with an acceleration of $10 \, \text{m/s}^2$ . Calculate the force of the body.

Identify the given values.
Mass ( $m$ ) $= 4.5 \, \text{kg}$
Acceleration ( $a$ ) $= 10 \, \text{m/s}^2$
Use Newton's Second Law of Motion to find the force.
The formula for force is $F = m \times a$ .
Substitute the values into the formula and calculate.
$F = 4.5 \, \text{kg} \times 10 \, \text{m/s}^2$ $F = 45 \, \text{N}$
The unit for force is Newtons (N).

The force of the body is $\boxed{\text{45 N}}$ .

2) Give 3 examples of Newton's Second Law of Motion.

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass ( $F=ma$ ).

Here are three examples:
- Pushing a shopping cart: The harder you push (more force), the faster it accelerates. If the cart is full (more mass), it accelerates less for the same push.
- Kicking a soccer ball: The force of your kick determines how quickly the ball accelerates and how far it travels. A harder kick results in greater acceleration.
- A car accelerating: When a car's engine applies a force to the wheels, the car accelerates. A more powerful engine applies a greater force, leading to greater acceleration, while a heavier car (more mass) will accelerate less for the same engine force.
