How far can a mother push a 20.0 kg baby carriage, using a force of 62.0 n at an angle of 30.0º to the horizontal, if she can do 2920 j of work?

54.4 m

Explanation:

The work done by the mother in pushing the carriage is equal to:

where

F is the force applied

d is the displacement of the carriage

is the angle between the direction of the force and the displacement

In this problem, we have the following data:

is the force

is the work done

is the angle between the direction of the force and the displacement

Re-arranging the equation above and substituting data, we find the displacement:

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

answer; how far out of place which the object finished relative to the starting location;
