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).

The projectile lands on the tabletop a horizontal distance R (the "range") away from where it left the launcher.

- 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.
