Answer:
The forces acting on the ball are gravity, friction and applied force.
Step-by-step explanation:
Tina rolls a ball across the floor. The forces acting on this ball are :
(1) Gravitational force : The force due to gravity act on this ball which is equivalent to, W = m × g
Where, m is the mass of ball and g is the acceleration due to gravity
(2) Frictional force : The force of friction always act in opposite direction of the applied force. It always opposes the direction of motion.
(3) Push (applied) : The force with which this ball is thrown is called applied force.
Hence, the correct option is (d) " all of these ".
