• 4%

• 2%

• 5%

• 10%

Which of the following is a scalar quantity?

A certain explorer went up North, then to the East, then finally went to the North again. If each part of her journey is represented as vectors, what will the vector sum look like?

•

A vector has a magnitude of 5.0 units and makes a 35-degree angle with the positive y-axis. What is its horizontal component?

• 4.1 units

• 2.9 units

• 3.5 units

• 5.0 units

A ball is thrown horizontally from the top of a cliff at the same time that another ball is dropped vertically from the same height. Which statement best describes their motion as they fall?

• Both balls reach the ground together since gravity pulls equally.

• The dropped ball lands first because it falls straight down.

• The thrown ball hits the ground first because it moves faster.

• The thrown ball lands farther away, following a curved path.

A soccer player kicks a ball at an angle of 30° above the ground. What happens to the horizontal component of the ball's velocity as it travels through the air?

• It remains constant as there is no horizontal force acting.

• It becomes zero when the ball reaches its peak height.

• It decreases because of air resistance acting against it.

• It increases due to gravitational acceleration.

Which of the following examples illustrates a non-contact force?

• A magnet attracting metal

• A person pushing a cart

• A car slowing down

• A book resting on a table
