Answer:
"There is a net force on the truck" is true about the forces acting on the truck.
Explanation:
When truck is in contact with the road and is moving, several forces acts on the moving truck.
The net force is a sum of the forces that acts in opposite directions and same directions.
When the truck is moving there is a normal force of the road acting upwards which is balanced by the weight of the truck that acts downward.
The correct answer for this question is " A.. The speed will i<span>ncrease." The higher the temperature, the more energy it has, and making it to vibrate faster. Since it vibrates faster, then sound waves can travel at a higher speed. In other words, it will make the the speed to increase.</span>
Answer:
<h2>64.4 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question
mass = 9.2 kg
acceleration = 7 m/s²
We have
force = 9.2 × 7 = 64.4
We have the final answer as
<h3>64.4 N</h3>
