16)You are pushing a 55N lawnmower across the yard. Its handle makes a 55 degree angle with the ground. What force are you exerting on the handle?

A)1 N
B)67.1 N
C)95.89 N
D)3025 N

I got C

17)Two men pull a 31 kg box with forces 9.7 N and 7.6 N in both directions. Find the resultant acceleration of the box and the direction in which the box moves.

A)2.1 m/s^2 to the left
B)2.1 m/s^2 to the right
C)6.8 x 10^-2 m/s^2 to the left
D)6.8 x 10^-2 m/s^2 to the right

I got A

  1. 16) Insufficient data for any answer. One needs to know the frictional and lawn-cutting resistance force, and whather the lawnmower is accelerating. You can push with any force you like on a 55N (weight)lawnmower. It's weight is supported by the vertical ground force on the wheels, not you pushing the handle.

    Whoever assigned that problem should not be teaching physics

    17) Wrong. Net force = 2.1 N. Divide than by mass for the acceleration. It will be in the direction of the larger force
