* Force (F) = 150 N * Distance (d) = 2.5 m * Work (W) = Force x Distance * W = F x d * W = 150 N x 2.5 m * W = 150 x 2.5 = 375 J Therefore, the work done by Pepito in pushing the table through a distance of 2.5 m with a force of 150 N is 375 J.

37. Formula:
W = F x d
Where:
W – work
F – force applied
d - distance

38. Force is measured in
newtons (N).
Distance is measured in
meters (m).
Work is measured in
newton-meters (N.m) or
Joule (J) – in honor of James Prescott Joule for
his accomplishment in the study of work and energy.

39. 50 N
DISTANCE
10 m
WORK = ?

40. GIVEN:
F = 50 N
d = 10 m
W = ?
FORMULA:
W = F x d
SOLUTION:
W = 50 N x 10 m
W = 500 J

41. Pepito exerted 150 N in pushing
a table through a distance of
