What is the speed of an object at rest

sammy [17]

The speed of an object is measured by calculating the distance it travels per unit time.
The formula in Physics for calculating speed is = distance/ time.

Since an object at rest is not covering any distance, the speed is always assumed to be 0 m/s.

What’s the velocity of a ball falling with 100 joules of kinetic energy and a mass of 2 kilograms

ohaa [14]

Answer:

the velocity is 10 m/s

Explanation:

Using the expression for kinetic energy we have:

$Ek=\frac{1}{2} *m*v^{2} \\\\Ek=100J\\m=2kg\\v=\sqrt{(2*100/2)}\\ v=10[m/s]$

A truck loaded with sand accelerates along a highway. The driving force on the truck remains constant. What happens to the accel

pickupchik [31]

Answer:

Acceleration will increase.

Explanation:

The relation between force, mass and acceleration according to the Newton's second law of motion is given as:

F = ma

We are given that the driving force on the truck remains constant, so F is constant here. We can rewrite the above equation as:

$a=\frac{F}{m}$

Since, F is constant, the acceleration of the truck is inversely proportional to the mass.

There is a hole at the bottom of the truck through which the sand is being lost at a constant rate. Since, the sand is being lost, the overall mass of the truck is being reduced.

Since, the acceleration of the truck is inversely proportional to the mass, the reduced mass will result in an increased acceleration.

So, the acceleration of the truck will increase.

8. What is the rate of change in an object’s position?

adelina 88 [10]

A similar but separate notion is that of velocity, which the rate of change of position. Example . If p(t) is the position of an object moving on a number line at time t (measured in minutes, say), then the average rate of change of p(t) is the average velocity of the object, measured in units per minute.
