A toy dart gun shoots a dart. If the initial total momentum of a tennis ball and tennis racket is +10 kg•m/s, then the final total momentum of the system after the racket hits the ball must be...

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

grav forces affect all objects magnetic forces affect magnetic objects and electric currents
