Question
For the lawn mower dipicted on page 138 of the text, suppose the person is exerting a force directed = 22 below the horizontal, and that the firctional force on the mower is f = 12 N. There are four external forces on the mower. Draw a free body diagram. (a) Calculate each of the four forces on the lawn mower, and label each force on your free body diagram with its magnitude (some number of Newtons). (Hint: You must sum the forces in the x-direction and the y-direction in order to do this.) (b) If the mower begins from rest at the origin, find it’s speed and location after t = 1.5 s. (Openstax textbook)
Explanation / Answer
free body diagram of lawn mover.this will help you a lot
resolve force components in x dirextion and ydirection
Fapplied*cos22-frictionalforce=0
Fapplied=12/cos22
=12.94N
Fnormal=Fapplied*sin22
=12.94*0.374
=4.847N
some information is needed to find out velocity
