-- The driver of the car says that the speed of the fly is zero.

-- An on-looker sitting on a park bench as the car passes him says that the speed

of the fly is 80 kph.

-- Both are correct, since there's no such thing as the "real speed", and speed is

always referred to something.

How would you explain this You are riding in a car at 80kmh A fly trapped in the car rests on your shoulder Describe the speed of the fly using two different reference points?

The fly is motionless, compared to your shoulder or the rear-view mirror. The fly is traveling at 80 km/hr with reference to the street signs on the side of the road. Assuming that traffic is going 80 km/hr each way, the fly is traveling at 160 km/hr with respect to the oncoming traffic in the other lane.


What is the acceleration of a car going a constant speed of 100?

If the car is going at a constant speed of 100 km/h, then its acceleration is zero. Acceleration measures the rate of change of velocity, and since the car's speed is not increasing or decreasing, there is no acceleration.


Assuming a car is front wheel drive and assuming the car does not spin out on the truck. If a car pulls onto a truck going 65mph and the truck is going 60mph how fast will the car be traveling?

If the car pulls onto the truck while maintaining a speed of 65mph, and the truck is moving at 60mph, the car's overall speed will be 65mph. The car's speed does not change by being on the truck, it merely matches the truck's speed.


How Does the Slope Change Car's Speed?

The slope of a surface can affect a car's speed by influencing the force of gravity acting on the car. Going uphill will slow the car down as gravity works against the car's forward motion, while going downhill will speed the car up as gravity provides additional force in the direction of motion. Overall, steeper slopes will have a greater impact on the car's speed than gentle slopes.


A truck and a car are traveling down the highway at the same speed If the truck has a greater mass than the car how do their kinetic energies compare?

The kinetic energy of an object is directly proportional to its mass and speed. Since the truck has a greater mass than the car but they are traveling at the same speed, the truck will have more kinetic energy than the car.
