Two kids push a 100 N toy car. Biff pushes 30 N to the right while his older brother Buff pushes at 50 N to the left. Draw a free body diagram of the car. Draw a free body diagram of the car. Label all forces.
What is the net force on the car?
Will the car accelerate? If so, in what direction is the acceleration?

Explanation:

Since forces are acting in opposite direction

Net force on the car = 50 - 30 = 20 N

mass of car

= weight / g

= 100 / 10

m = 10 kg

acceleration of car = net force / mass

= 20 / 10

= 2 m /s² .

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
