Answer #1

speed is only scalar quantity hence direction of motion, velocity and accelerations options are wrong.

because direction of motion is a unit vector quantity

velocity and accelerations are vector quantities.

If both boats are of same speed means they may or may not be at same position also.

How ever to say directly the two boats are of same speed if and only if they travel equal distances in equal intervals of time. so there may be chance to get the same position in this case.

so right answer is a) position.

Speed means the absolute value of the velocity, hence it is always non-negative. While the sign of the velocity indicates the direction of the motion, the speed is insensitive to the direction. For example, speed is the value displayed by car’s speedometer; it does not indicate the direction of driving (e.g., northbound versus southbound). At time t = 0 seconds (s) an object has zero velocity and it starts a free fall from the altitude of 1200 metres (m) above...

Two cars of the same mass drive with the same speed of 60 miles per hour. They approach each other at an angle of 90 degrees. What is the speed (in miles per hour) of the two cars, after they undergo a completely inelastic collision and continue to move jointly into the 45 degrees direction? (Moving jointly into the 45 degrees direction means that after the collision the two cars move together into the direction right between the directions of...

You might have a small buggy or such that moves at a constant speed, like a remote control car or the like. Turn the buggy on, and hold it just above the ground for a second. Now let it go, and watch the motion. Make predictions on what you expect to see as far as graphs of the motions - position, velocity, and acceleration.
