Answer:

31km/h

Step-by-step explanation:

Step one:

given data

speed of bus= 35km/h forward

speed of ball= 4km/h backwards

`Step two:

Required

the magnitude of the velocity of the ball relative to the ground is the net velocity

that is

=35-4

=31km/h

The velocity of the ball relative to the ground is 31km/h
