Particles A and B of masses mkg and (1 β m) kg respectively are attached to the ends of a light inextensible string which passes over a fixed smooth pulley. The system is released from rest with the straight parts of the string vertical. A moves vertically downwards and 0.3 seconds later it has speed 0.6 ms-1
Find
(i) the acceleration of A
(ii) the value of m and the tension in the string.

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earthβmoon (center-to-center) distance is 3.82 Γ 10^8 m, earth's radius is 6.37 Γ 10^6 m, moon's mass is 7.36 Γ 10^22 kg, and earth's mass is 5.98 Γ 10^24 kg.
