Concept explainers
A block of mass 0.500 kg is pushed against a horizontal spring of negligible mass until the spring is compressed a distance x (Fig. P7.79). The force constant of the spring is 450 N/m. When it is released, the block travels along a frictionless, horizontal surface to point Ⓐ, the bottom of a vertical circular track of radius R = 1.00 m, and continues to move up the track. The block’s speed at the bottom of the track is υⒶ = 12.0 m/s, and the block experiences an average friction force of 7.00 N while sliding up the track. (a) What is x? (b) If the block were to reach the top of the track, what would be its speed at that point? (c) Does the block actually reach the top of the track, or does it fall off before reaching the top?

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_forward
- 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. At t = 0 a new force F(t) is applied that has components Fx(t) = k₁ + k₂y Fy(t) = k3t where k₁, k2, and k3 are constants.

An up- ward force of 200 N is applied as shown. (a) Draw three free-body diagrams: one for the 6.00 kg block, one for B the 4.00 kg rope, and another one for the 5.00 kg block. For each force, indicate what object exerts that force. (b) What is the acceleration of the system? (c) What is the tension at the top of the heavy rope?
