A block (mass 5 kg) is initially moving to the left at 10 m/s. After hitting the wall, the ball is moving to the right at 5 m/s. What is the impulse of the net force on the ball during its collision with the wall?

The impulse of the net force on the ball during its collision with the wall is 25N

Explanation:

Step one :

Given data

Mass =5kg

Velocity v1=10m/s

Velocity v2=5m/s

The equation for impulse is given as

P=m(v1-v2)

Where P =impulse

Substituting our values into the equation we have

P=5*(10-5)

P=5*5

P=25N

The impulse 25N

What is impulse?

Impulse is the change of momentum of an object when the object is acted upon by a force for an interval of time.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
