How to calculate kinetic energy using negative numbers

Physics
1 answer:
Rudik [331]3 years ago
8 0

The kinetic energy of a moving object is

         (1/2) (object's mass) (object's speed squared).

Unless the object's mass is negative or its speed is imaginary,
you'll never need to deal with negative numbers here.

With that push, they have accelerated their masses, which means they have _____ of their bodies.
nexus9112 [7]

As per Definition of acceleration we know that rate of change in velocity of object is known as acceleration

a = \frac{v_f - v_i}{\Delta t}

so when we apply push on an object that push or applied force will change the velocity of object always

so correct answer must be

a.) changed the velocity

An astronaut on an alien planet drops a rock into a crater which is 100 meters deep. The rock hits the bottom of the crater 4 se
Semmy [17]

Answer:

The gravity on this planet is stronger than that of earth.

Explanation:

First we need to find the acceleration due to gravity value of this planet to compare its gravity force with that of the earth. Hence, we will use second equation of motion:

h = Vi t + (0.5)gt²

where,

h = height or depth of crater = 100 m

Vi = Initial Velocity of rock = 0 m/s

t = time = 4 s

g = acceleration due to gravity on this planet = ?

Therefore,

100 m = (0 m/s)(4 s) + (0.5)(g)(4 s)²

g = (200 m)/(16 s²)

g = 12.5 m/s²

on earth:

ge = 9.8 m/s²

Since,

ge < g

Therefore,

<u>The gravity on this planet is stronger than that of earth.</u>

The velocity of an object is positive and steadily increasing. Which of the following graphs represents how the acceleration of
stiv31 [10]
If an object's velocity is steadily increasing it means that the acceleration is constant at a certain value.

Choice A shows an acceleration of zero which would only be true if the object was not moving or if its velocity was not changing.

Choice B gives us a graph showing acceleration increasing over time and is therefore incorrect.

Choice C is correct because the acceleration is constant. Steadily increasing tells us that the acceleration is fixed at a certain value.

Choice D is incorrect an represents a constant negative acceleration. This would be the case if the object was steadily decreasing in velocity.
