- 27) I caught me a big shark, one having a mass of 650 kg. It is held up by a strong pole (solid black in the figure) that makes an angle of 55.0° with the horizontal and an attached cable (light brown in the figure) at its end. The pole is uniform in construction, 4.00 m long, and has a mass of 50.0 kg. The cable makes an angle of 35.0° with the horizontal. Determine the tension in the cable, and the x and y components of the force exerted at the base of the pole. Start off by drawing the Tension T on the cable and the x and y- forces at the base of the pole. 35° 55°Please asapA house painter stands 3.00 m above the ground on a 5.00-m-long ladder that leans against the wall at a point 4.70 m above the ground. The painter weighs 663 N and the ladder weighs 108 N. Painter Ladder Driveway Wall 4.70 m 3.00 m Assuming no friction between the house and the upper end of the ladder, find the force of friction that the driveway exerts on the bottom of the ladder. If the force of friction is away from the wall, enter a negative value and if the force of friction is toward the wall, enter a positive value.
