Question

A body of mass 2 kg is placed on smooth horizontal plane, pulled by the force of 2 n then the velocity of the body after 3 s is

Answer 1

Answer:

Step-by-step explanation:

as per given data

F= 5N , m= 2kg,

and according to Newton's laws

net force,F=ma

a=F/m=5/2=2.5 m/s sq.

S=ut+ 1/2at^2

where s is displacement

so, s= 0+0.5 * 2.5* 25=31.25

and, work = force * displacement

=5* 31.25

=156.25 joules
