An object with a mass of 375g is moving with a constant velocity. It has a force of -20 N applied to it. Determine the acceleration of the object. What is happening to the object?

The acceleration of object is - 0.53 and it is moving in opposite direction.

Explanation:

Given

mass of object, m = 375 kg

Force applied, F = -20 N = -20 Kg

acceleration of object, a = ?

We know that F = ma, where f is force, m is mass and a is acceleration.

therefore, a = F/m

                    = -20 Kg / 375 Kg

                    = - 0.53

When acceleration is negative, it means either the value  is decreasing or the object is moving in opposite direction.

In given case force is negative and so the negative value of acceleration means the object is moving in opposite direction.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
