W = ∫ F.dx = Area of F -x curve so
A)
Area between x = 0 to 2
W = 1/2*base *height = 1/2*2*1 = 1 J answer
B)
W = area of rectangle = (6-5) *3 = 3 J ans
C)
W = 1/2*( 15-12) *1.5 = 2.25 J ans
D)
w = 1/2*5*3+ ( 10-5) *3 + 1/2* ( 15-10) *3 = 30 J
E)
W = change in KE
30 = 1/2*m*v^2 = 1/2*5.4*v^2
v≈3.33333 m/s ans
F)
P = W/t = 30/12 =2.5 Watt
