Question

A girl pulls her school box with a force of 78N inclined at 27degrees to the ground caculate
i.the paert of the force moving the box along the ground
ii.the work done if the displacement is 125m
please this is urgent​

Answer 1

Answer:

i) 69.5

ii)if displacement cosidered in a plane,

then W= 78×125 (W=F.d)

if displacement is given to be along ground then

W=69.5×125

Explanation:

i)F along ground = 78cos(27°)

ii)if displacement cosidered in a plane,

then W= 78×125 (W=F.d)

if displacement is given to be along ground then

W=69.5×125
