IP A gardener mows a lawn with an old-fashioned push mower. The handle of the mower makes an angle of 39 ° with the surface of the lawn. Part A If a 90.0-N force is applied along the handle of the 17-kg mower, what is the normal force exerted by the lawn on the mower? Express your answer using two significant figures. Π ΑΣφ N = N Submit Request Answer Part B If the angle between the surface of the lawn and the handle of the mower is increased, does the normal force exerted by the lawn increase, decrease, or stay the same? O Increases O Decreases O Stays the same Submit Request Answer

Determine the resultant ?R of the three tension forces acting on the eyt bolt. Find the magnitude of R and the angle θx which R makes with the positive x-axis.  Note that F1= 563 N, F2= 345 N and F3= 296 N.

Three rugby players are pulling horizontally on ropes attached to a box, which remains stationary. Player 1 exerts a force F equal to 200 N at an angle 0, equal to –60.0° with respect to the +x-direction, as shown in the figure. Player 2 exerts a force F2 equal to 300 N at an angle 02 equal to 37.0° with respect to the +x-direction. The view in the figure is from above. Ignore friction and note that gravity can be ignored in this problem. Determine the force F3 exerted by player 3. State your answer by giving the x- and y-components, F3, and Fay, respectively. F, F3x -339.59 N F3y N Player 3's rope breaks, and player 2 adjusts by pulling with a force of magnitude F; equal to 250 N at the same angle as before. Defining angles above the x-axis as positive and those below as negative, at what angle 0 is the acceleration of the box relative to the +x-direction? The magnitude of the acceleration is measured to be 10.0 m/s?. What is the mass m of the box? kg m = F TOOLS x10

1. A 20,000 pound truck is parked on a 15° slope. Find the force required to keep the truck from rolling down the hill (that is, find the magnitude of the vector component of the weight of the truck that is parallel to the slope). 2.Determine the vector v with magnitude of 30 that makes an angle of 120° with the positive xaxis. State the vector in either ordered set or unit vector notation with components written as exact values (simplified radical form).

n a carbon monoxide (CO) molecule, the distance between the oxygen atom and the carbon atom is 1.13 × 10-10 meters. The mass of an oxygen atom is 16 atomic mass units (amu) and the mass of a carbon atom is 12 amu. How far from the oxygen (O) atom is the center of mass of the molecule, in meters? Justify your answer using your equations and rationale used.
