(i) • there is force applied to an objects
• the object moves
• the object moves in the same direction as the direction of the force
(ii) workdone = force x distance
= 23 x 34
= 782Joules
W = 1/2k*x^2.
k = spring constant = 2500 n/m.
x = distance = 4 cm = 0.04m (convert to same units).
W = 1/2(2500)(0.04)^2 = 2J.
I’m not really sure but I think it’s D type 1 lever
