Question

force of 100 N displaces an object through a distance of 20 m. The angle between force and displacement vectors is 60 degree, The work done by the force is​

Answer 1

Explanation:

$as \: we \: know \: that \: work \: done \: at \: an \: angle \: with \: horizontal \: direction \: \: \: \: \: \: \: \: \:$

$work \: done \: = fcostheta \: \times s \\ \\ w = 100 \times 1 \div 2 \times 20 \\ \\ \\ w = 50 \times 20 \\ \\ work \: done \: = 1000joule$
