1 mile = 5,280 feet
77 miles/hour = (77 x 5280) feet/hour
1 hour = 3,600 seconds
(77 x 5280) feet/hour = (77 x 5280) / 3,600) feet per second
Distance covered in 3 seconds = (3 x 77 x 5,280 / 3,600) = 338.8 feet
When objects are far away, the distance of the object is much greater than the distance that you are moving. Hence, there is little change in the relative position of you and the object.
10 x 30 = 300 metres.
320 meters
You haven't given us any information from which to calculate that speed. As far as we know from the question, the object isn't moving at all.
speed
(25 meters per second) x (1.5 seconds) = 37.5 meters
That would be distance.
440 feet
576 feet
If he doesn't move, your likely to far away from him. Try moving closer to him and he will probably start moving.
There is no such thing as an amount of force needed to move a certain distance. Asteroids, comets, moons, and planets have been moving trillions of miles through space for billions of years with either no force on them at all, or no force in the direction they're moving. You may have heard of Newton's First Law. It says that an object with no forces acting on it keeps moving in a straight line at a constant speed, which is kind of another good way of saying that it can move as far as you want it to with no force on it.
