can someone please explain these problems. thanks

18. 19. 20. 21. A 2.50 m uniform ladder weighs 200.0 N. A man places the ladder against a smooth (i.e. "frictionless") wall 2.00 m above the ground as shown in diagram below (not drawn to scale). The man. who weighs 7.80 x 102 N. climbs up and stops 50.013111 from the top of the ladder. The right gure below shows the free body diagram of the ladder with the relevant forces labelled (strictly speaking the wall should not be shown for the free body diagram). (a) (b) The value of F\". is, (a) 708 N (b) 48 N (c) 980 N (d) 543 N (e) 177 N The value of FM is. (a) 708 N (b) 48 N (c) 980 N (d) 543 N (e) 177 N The value of F}, is, (a) 708 N (b) 48 N (c) 980 N (d) 543 N (e) 177 N Continued overleaf 23 The magnitude and direction of the resultant force of the ground on the ladder (at the base) is. (a) 1.74 x 103N at 53 above the horizontal. (b) 1.12 x 10'I N at 61" above the horizontal. (c) 7.15 x II]2 N at 47 above the horizontal. (d) 5.79 x 10'- N at 53 above the horizontal. (e) 2.12 x 102N at 43 above the horizontal
