You are playing darts in an elevator that is rising at a constant speed. Should you still aim at your target the way you would normally do, or should you aim higher, or lower? Explain.
Note that the problem states the elevator is rising a constant speed, and hence is not accelerating.Ah you are right. But in the period of time during which the dart is in the air, is the dart being pulled up like the rest of the elevator?
Doesn't what I'm saying still matter though? If it is rising at a constant speed it means there is an acceleration equal to 9.8 m/s^2 up. The dart, in midair, doesn't feel this acceleration.Note that the problem states the elevator is rising a constant speed, and hence is not accelerating.
Doh, yes you're definitely right. I thought you were implying there were pseudo-forces present in the elevator.Doesn't what I'm saying still matter though? If it is rising at a constant speed it means there is an acceleration equal to 9.8 m/s^2 up. The dart, in midair, doesn't feel this acceleration.
No, there is no acceleration if the velocity is constant.Doesn't what I'm saying still matter though? If it is rising at a constant speed it means there is an acceleration equal to 9.8 m/s^2 up. The dart, in midair, doesn't feel this acceleration.
Of course, but the second the 'dart' leaves the thrower's hand, it's no longer being pushed up by the force of the rising elevator cart (mediated by your hand) and therefore it feels a downward force equal to g, right?No, there is no acceleration if the velocity is constant.
It already feels a force downward equal to g before the throw. (Just like a dart supported by someone on the ground) Once it is released it is rising at the same velocity as the rest of the elevator and will act identically to a dart thrown on the ground.Of course, but the second the 'dart' leaves the thrower's hand, it's no longer being pushed up by the force of the rising elevator cart (mediated by your hand) and therefore it feels a downward force equal to g, right?
No, different acceleration is experienced due to altitudeYou are playing darts in an elevator that is rising at a constant speed. Should you still aim at your target the way you would normally do, or should you aim higher, or lower? Explain.

NO, :)No, different acceleration is experienced due to altitude
but the probability could be the same
Doing that on top of the high mountain is the same.. no acceleration but different g "acceleration due to gravity due to altitude" (should have use that phrase in my last post).NO, :)
read the several previous comments, The speed is constant, there is NO acceleration :)
