Question

**Problem 9:**

A hoist is used to lift a 780 kg car upward with an acceleration of 0.110 m/s².

a) What is the net force acting on the car?

b) What force was used to lift the car?

**Answers:**

a) 86 N

b) \(7.73 \times 10^3\) N

**Diagram Explanation:**

The image includes a diagram showing a car being lifted upward. There is an arrow pointing upwards alongside the car to indicate the direction of acceleration and the acceleration value \(a = 0.11 \, \text{m/s}^2\) is shown next to the arrow. The car is placed on a platform, visually representing the lifting mechanism of the hoist.

* Incorrect Newton's Third Law states that: a) A particle remains at rest or continues to move with a uniform velocity if there is no unbalanced force acting on it. b) The acceleration of a particle is proportional to the vector sum of forces acting on it, and is in the direction of this vector sum. O c) The forces of action and reaction between interacting bodies are equal in magnitude, opposite in direction, and collinear. O d) The velocity of a particle is proportional to the vector sum of forces acting on it, and is in the direction of this vector sum.
