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?

A projectile is shot from a launcher at an angle e, with an initial velocity
magnitude v., from a point even with a tabletop. 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.

- 2. 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_forward4.56 ... CALC An object of mass m is at rest in equilibrium at the origin.
