You push a cart with mass 20 kg forward, giving it an acceleration of 2 m/s2. how much force did you apply?

The force is 40 N.

Explanation:

Given that,

Mass = 20 kg

Acceleration = 2 m/s²

We need to calculate  the force

The force is the product of the mass and acceleration.

Using newton's formula

Where, m = mass

a = acceleration

Put the value into the formula

Hence, The force is 40 N.

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

technology is the application of the knowledge gained by science.
