Question

WORK DONE BY AN APPLIED FORCE OF 20 N ON A BODY MOVING ON A ROUGH HORIZONTAL PLANE WITH A UNIFORM VELOCITY OF20MS_ 1 IN ONE SECOND ​

Answer 1

Answer:

As we can See;

F=20N

V=20m/s

T= 1 sec

Explanation:

Now, speed= distance/time or velocity=displacement/time

20=D/1

D=20

Workdone= force × displacement

W=20×20

W=400N/m

Hope it helps
