Question 1: Mandy stands on a weighing scale inside an elevator that accelerates vertically upwards. The forces on Mandy are her weight W and the reaction force R from the scale. The reading of the scale is: (options A,B,C,D): (A) R+W (B) W (C) R (D) R-W
Question 2: A rock climber descends a cliff face by abseiling down it. The mass of the climber is 64 kg. At a time the climber pauses, the rope under tension is held at an angle of 35 degrees to the vertical. What is the magnitude of the horizontal force acting on the climber from the cliff face?
Options: A) 300N B) 360N C) 440N D) 510N
an explanation as to how you got the answer to question 2 would be nice! Thanks.

mg cos35= tension(t)
whose horizantal component is the force acting on the climber.
sorry... if its a mistake
