Q. If the net force acting on an object is in the positive x-direction, the object moves only in the positive x-direction.
It is not true, the object will accelerate only in the x-direction, but it may be traveling in the y-direction and it could continue to do so making the path it follows a parabola. Think about a ball kicked off a cliff. There is a net force only in the y-direction (gravity) so the ball will accelerate downwards while continuing with a constant horizontal velocity.
A copper pot with mass 0.500 kg contains 0.170 kg of water ata temperature of 20.0ºC. A 0.250-kg block of iron at85.0ºC is dropped into the pot. Find the final temperature, assumin
