Physics problem about moving objects?

Question

suppose you tossed a ball straight up while in a car moving ahead at constant speed, where would the ball land? justify

Thank you for answering my question

Answer 1

in a world with no air resistance,

if you toss the ball straight up, then it will fall on the ground exactly at the point on the road where you threw it.

think of it this way- what other force, other than your hand, is acting on the ball? answer: none! the car doesn't exert any force on the ball, it exerts force in the direction it is going down the road.

Answer 2

You would catch it (assuming no wind resistance). The ball is moving at the same speed as the car. The car isn't accelerating, therefore the ball will continue to move at the same speed, forming an arc, and landing back on the car. ( I don't think I worded it right the first time)

If you have trouble visualizing, imagine being in a car, and doing this experiment, but on a smaller scale. Samething in these type problems.

The concept is called inertia. Objects at rest tend to stay at rest and objects in motion tend to stay in motion UNLESS acted upon by an outside source. In the real world, air resistance and a myriad of other forces would act upon the ball, however, in these Newtonian exercises, all of those variables are assumed out. It's just to make sure that you understand the concept.

Miss Advice is DEAD wrong! The ball is moving at the exact same speed as the CAR while it is in the car!!! If the car is going at 50 mph, the ball will not suddenly stop going 50 mph!!! Even in the real world with air resistance, the ball would take a some amount of time and distance to come to a complete stop!

Answer 3

The answer depends on how high the ball goes and its co-efficient of friction. Initially, ball has a horizontal velocity the same as the car, but begins to decelerate as soon as it meets wind resistance. Similarly, the ball decelerates from its initial vertical velocity as soon as it leaves your hand. In the time it takes to go up, stop and fall, it will move forward at a decreasing rate. So it will fall somewhere between the spot on the road where it was thrown and the car.

Answer 4

Air resistance would cause the ball to slow and it would not land back in your hand, but behind you, if the car were open. If closed, the ball would land back in your hand, because the frame of refrence is the car floor,
and the motion of the car is irrelevant to the ball's flight.
If the windows were large an acute observer on the ground would see the ball descibe an arc, and land back in the hand.

Answer 5

it will go foward as fast as the car is moving. If you jump, you appear to land in the same spot, however the earth is moving 1040mph, but because you were moving at the same speed as the earth when you jumped, you move foward along with the earth. Why dont you tell your moving so fast? Newton proved it was impossible to detect motion without any frame of reference.
Even running with your eyes closed, you feel the wind going down your face.

Answer 6

In your hands or lap or watever I mean at the point from where it was thrown because U & the ball are not in any relative motion w.r.t. the car

Answer 7

Hi Trick question. Straight up from the earth? The car? Different answers. From the earth it would land under the point where you threw it.

Answer 8

well, it would land behind the car i guess if you take into account wind resistance.

Answer 9

On your head...
