A) 6i + 5j-kB) 6i + 5j + kC) 7i-j + kD) 10i + 5j + 3kE) 3i + 2karrow_forwardUna persona ejerce una fuerza horizontal F = 150 [N] (dirigida hacia la izquierda) sobre el aparato de prueba que se muestra en el dibujo.Encuentre la fuerza horizontal M (magnitud y sentido) que ejerce el bíceps sobre su antebrazo (L= 0.30 [m], h = 0.040 [m]), suponiendo que el codo se puede modelar como una articulación perfecta.arrow_forward
- in solving for the position-coordinate postion for a problem involving a system of two or more cords wrapped around pulleys.than the position of a point on one cord must be related to the position of a point on another cord. TRUE OR FALSE?arrow_forwardWhen you use the approximation for a pendulum,you must specify the angle in(a) radians only.(b) degrees only.(c) revolutions or radians.(d) degrees or radians.arrow_forwardA particle of mass 7 kg starts at A with initial velocity 3.2 m/s for H=5.4 m and h =3.8 m, radius of curvature at B is 4.2 m and at C is 24 m.arrow_forward
- Consider the two vectors G = (4.55 N)i + (4.99 N)j + (8.16 N)k and H = (2.08 N)i + (5.89 N)j. 1. What is the component of G along H in units of N? compHG = _______arrow_forwardA person bends forward to lift a load with his back. To see that this is not a good way to lift, we will find the large induced force R = Rx(i) + Ry(j) occurring in the spine by lifting a 200-N object. The spine and the upper body are represented as a uniform horizontal rod of weight 350 N, pivoted at the base of the spine. The erector spinalis muscle, attached at a point 2/3 of the way up the spine, maintains the position of the back with tension T. The angle between the spine and this muscle theta = 12 degrees. Find the magnitude of force R at the base of the spine.arrow_forwardThe staples inside a stapler are kept in place by a spring with a relaxedlength of 11.5 cm. The spring constant is 51.0 N/m. How much elasticpotential energy is stored in the spring when its length is 8 cm?arrow_forward
- Show that when A+B=C then A2+B2+2ABcos , where is the angle between vectors A and B .arrow_forwardExpress the following angles in radians: (a) 20.0°, (b) 50.0°, (c) 100°. Convert the following angles to degrees: (d) 0.330 rad, (e) 2.10 rad, (f) 7.70 rad.arrow_forwardANSWER ASAP. WILL GIVE AN UPVOTEarrow_forward
