Here ,
Using second law of motion
net force acting = mass * acceleration
as the boats move with constant speed , acceleration = 0
net force acting = 0 *mass
net force acting = 0 N
hence , the net force acting on speedboat A is equal to net force acting on speedboat B.
as the acceleration of both boats is zero
Two speedboats are moving at constant speeds on a straight stretch of a racecourse. At the...

1. A moving truck has momentum. If it moves four times as fast, its momentum is as much. 2. Two carts, one three times as heavy as the other, move down a hill at the same speed. Compared to the lighter cart, the momentum of the heavier cart is as much. 3. A bus is traveling at highway speeds when the momentum of an unlucky bug is suddenly changed as it splatters into the...
Joe, standing near a straight road, records the sound of the
horn of a car traveling at a constant speed. The recorded frequency
as a function of the car's position along the road for trials at
different car speeds is accurately graphed below.

NTSB-QRT19: STUDENT PUSHES TWO SLOWING BLOCKS-FORCE ON BLOCK A student pushes the two blocks to the right. Block A has more mass than block B There is friction between the blocks and the table. (i) For the situation where the blocks are slowing down, which of the following statements is true about the magnitude of the forces a) The force that block exerts on block is greater than the force that block exerts on block b) The force that block....
8. Two cars, P and Q, travel in the same direction on a long, straight section of a highway. Car P passes car Q, and is adjacent to car Q at time to a. Suppose that car P and car Q each move with constant speed. At time t, is the magnitude of the instantaneous velocity of car P greater than, less than, or equal to the magnitude of the instantaneous velocity of car Q? Explain. Suppose instead that car...
