Ahorizontal force of 2500 n is applied for a time of 30 seconds to the car mass of 1000 kg if the car is at rest and friction is negligible determine the distance travelled by the car
labor day, patriot day, leaves start to change colors then fall from the tree
their final velocity is 0.48 m/s.
we can use conservation of momentum to calculate the magnitude of the final velocity.
momentum before collision is equal to the momentum after collision
here, v is final velocity , assuming right side velocity as positive, and left side velocity as negative.
here, negative sign indicates that they both will move in left direction.
