Question

Draw a sketch and also a good FBD to identify the relevant forces doing work. Pay attention to the units and positive or negative value of the quantities. 2. A person pushes on a hockey puck with their stick at an angle so the vertical force is 22 N [down] and the horizontal force is 45 N [forward]. Assume the ice is frictionless.

Answer 1

Given:

The force is in the vertical direction is

`F_1=22\text{ N}`

The force is in a horizontal direction

`F_2=45\text{ N}`

velocity of the puck is

`v=22\text{ m/s}`

time during which puck is in contact with hockey is

`t=3\text{ s}`

Required:

(1)Actual force on puck is
