Chapter 11, Problem 11.10CQ
A cat usually lands on its feet regardless of the position from which it is dropped. A slow-motion film of a cat falling shows that the upper half of its body twists in one direction while the lower half twists in the opposite direction. (See Fig. CQ11.10.) Why does this type of rotation occur?

- 4.4 A man is dragging a trunk up the loading ramp of a mover's truck. The ramp has a slope angle of 20.0°, and the man pulls upward with a force F whose direction makes an angle of 30.0° 75.0° with the ramp (Fig. E4.4). (a) How large a force F is necessary for the component Fx parallel to the ramp to be 90.0 N? (b) How large will the component Fy perpendicular to the ramp be then?

The projectile lands on the tabletop a horizontal distance R (the "range") away from where it left the launcher. Set this up as a formal problem, and solve for vo (i.e., determine an expression for Vo in terms of only R, 0., and g). Your final equation will be called Equation 1.arrow_forward2. A projectile is shot from a launcher at an angle 0,, with an initial velocity magnitude vo, from a point even with a tabletop. The projectile hits an apple atop a child's noggin (see Figure 1). The apple is a height y above the tabletop, and a horizontal distance x from the launcher. Set this up as a formal problem, and solve for x. That is, determine an expression for x in terms of only v₁, o,y and g. Actually, this is quite a long expression. So, if you want, you can determine an expression for x in terms of v., 0., and time t, and determine another expression for timet (in terms of v., 0., y and g) that you will solve and then substitute the value of t into the expression for x. Your final equation(s) will be called Equation 3 (and Equation 4).arrow_forward
