Which mathematical relationship best describes a graph of gravitational field strength versus distance? (one of the 3 pictures attached or none of the above?)

Answers

The gravitational force between two masses is proportional to

(mass-1) x (mass-2) / (the distance between them)-squared

Do you see (distance-squared) in the denominator there ?

That steers you straight to the function [ y proportional to 1/x² ] ... in the middle.

A 50 kg ball rolls down the street at 5 m/s.
Calculate the momentum of the ball.

Answers

The momentum of the ball is250 Kgm/s

Given the following data;

Mass = 50 kg

Velocity = 5 m/s

To find the momentum of the ball;

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. It is a vector quantity and as such has both magnitude and direction.

Mathematically, momentum is giving by the formula;

$Momentum = mass\; * \; velocity$

Substituting into the formula, we have;

$Momentum = 50 * 5$

Momentum = 250 Kgm/s

Therefore, the momentum of the ball is250 Kgm/s

Answer: 250kg m/s

Explanation: You multiply 50kg and 5m/s to get 250kg m/s

Is it possible for an object to move so that it produces an absolutely vertical line on the velocity-time graph? Explain.

Answers

Answer: No.

Explanation: If an object moved to produce a vertical line on the velocity-time graph, it would mean that it would move at an infinite speed with no change in time. Nothing moves at an infinite speed; it is just not possible.

If you wanted to look at it through a calculus lens, acceleration is the derivative of velocity. You can't take the derivative of a vertical tangent line, so the acceleration wouldn't exist. This isn't possible if an object is moving; it has to have either constant acceleration or a non-zero acceleration.
