1.	Ali pushes an object with a force of 50 N directed at an angle of 60o below the horizontal direction. Calculate the work that Ali has done on the object if the object moves 10 m horizontally. what is the answer
Answer» Answer: We KNOW frictional FORCE f=μN where N=normal force=mg Given SLIDING frictionμ=0.25 Thus, f=0.25×50×10=125N Hence Fnet=Fapp−f=575−125=450N Also we know ForceF=ma a=50450=9m/s2

Ali pushes an object with a force of 50 N directed at an angle of 60o below the horizontal direction. Calculate the work that Ali has done on the object if the object moves 10 m horizontally. what is the answer

Answer»

Answer:

We KNOW frictional FORCE f=μN where N=normal force=mg

Given SLIDING frictionμ=0.25

Thus, f=0.25×50×10=125N

Hence Fnet=Fapp−f=575−125=450N

Also we know ForceF=ma

a=50450=9m/s2

if train of length 200cm moving with constant velocity takes 10 sec to cross an electric pole, then the time taken cross an bridge of 400m is ?

Answer»

$\mathfrak{ \huge{ \red{ \underline{ \underline{Answer}}}}}$

Given :

=> A train of length 2m taked 10s to CROSS an ELECTRIC pole...

To Find :

=> Time requires to cross an bridge of length 400m...

Formula :

=> Velocity(v) of a particle in forms of displacement(d) and time(t) is given as..

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{ \pink{ \bold{v = \frac{d}{t}}}}$

Calculation :

=> velocity of train v = 2/10 = 0.2 m/s

=> with the help of this constant velocity time requires to cross a bridge..

=> t = d/v = 400/0.2 = 2000s

$\blue{ \huge{ \star}} \: \boxed{ \boxed{ \red{ \bold{time = 2000 \: s}}}} \: \blue{ \huge{ \star}}$

48.	Difference between unbalanced force and net force
Answer» Explanation: As we have SAID before, a net FORCE is the sum of all forces acting on an object. ... The object will speed up, slow down or change DIRECTION. An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an UNOPPOSED force that causes a change in motion.
