Question

The diagram at the right depicts a hockey puck moving across a horizontal, frictionless surface in the direction of the arrow XX. A constant force F shown in the diagram is acting on the puck. For the puck to experience a net force in the direction of the arrow XX, another force must be acting in which of the directions labelled A, B, C, D, E? (2.5 marks)

Answer 1

Given that,

A hockey puck moving across a horizontal, frictionless surface in the direction of the arrow XX.

A constant force F is acting on the puck

The experience a net force in the direction of the arrow XX, for the puck

We need to calculate the another force must be acting in which of the directions labelled

According to figure,

The object is moving in the XY direction, there is no horizontal component of the force.

So, the net force must have a horizontal component and a vertical component.

Hence, The another force must be acting in the direction of C.
