I had this question before can you show me the answer choices
Your basically breaking the sound beerier <span />
As we know that average speed is given by the ratio of total distance covered and total time of motion so we will have
now we have
distance covered = 40 meter
time taken by the bird = 10 minutes
now in order to find the average speed of the bird
so the average speed of the bird is 4 m/min
5 newton forward because the force of the engine is greater than the force of friction so that means the car is going forward.
You can think of this: when friction is greater than the force of an object its slowing down but when the force of the car is greater than the force of friction its speeding up.
Hope this helps
Work=Force*Distance so distance must be .82 meters
