Question
A fan and a sail are mounted vertically on a cart that is initially at rest on a horizontal table as shown in the diagram. When the fan is turned on, an air stream is blown towards the right and is incident on the sail. The cart is free to move with negligible resistance forces. After the fan has been turned on the cart will
Options
A.move to the right and then to the left
B.remain at rest
C.move towards the right
D.move towards the left
Solution
Sol. Impulse given by fan to sail through air = Impulse given by air to fan.
∴ Net impulse on system = zero
⇒ system remains at rest
