A 3) A flea jumps by exerting a force of1.22 10^-5 N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of1.14 10^-6 N on the flea. Find the direction and magnitude (in m/s²) of the acceleration of the flea if its mass is 6.0 10^-7 kg. (Let us assume that points to the right. We will consider this to be the+x direction and vertical to be the+y direction.)

Magnitude? m/s^2

Direction? Degrees

6 A)Suppose two children push horizontally, but in exactly opposite directions, on a wagon containing a third child. The first child exerts a force ofF₁ = 75.0 N, the second a force of F₂ =92.0 N, friction is 12.0 N, and the mass of the third child plus wagon is26.0 kg.

Calculate the acceleration (in m/s2).

B 3) Suppose your car was mired deeply in the mud and you wanted to use the method illustrated in the figure below to pull it out

1. What force would you have to exert perpendicular to the center of a rope to produce a force of11,500 N on the car if the angle is =3.10? (Enter the magnitude only.
2. Real ropes stretch under such forces. What force would be exerted on the car if the angle increases to 7.00 and you still apply the force found in part (a) to its center? (Enter the magnitude only.)
