# What is the kinetic energy of a body of mass 10 kg moving with a speed of 5 meters per second square?

## What is the kinetic energy of a body of mass 10 kg moving with a speed of 5 meters per second square?

= – 125 J (nagative sign indicates work done is opposite to the direction of motion)

## What is an object of 10 kg is moving with a speed of 2 meters per second?

Speed of the object (v) = 2 m/s. Kinetic Energy (K.E) = ½ mv2. = ½ (10)(2)2 ⇒ 20 joules. The kinetic energy of the object is 20 J.

## What is the kinetic energy of a 10 kg object moving at 5 ms?

The kinetic energy of the object is 125 J.

## What is the kinetic energy of a mass of 10 kg moves with a velocity of 4ms?

An object of mass 10 kg is moving with a uniform velocity of 4 ms-1. The kinetic energy possessed by the object is 80 J.

## What happens when a mass of 20 kg moving with a speed of 10 Metre per second collides with another stationary?

A mass of 20 k g moving with a speed of 10 m s – 1 collides with another stationary mass of 5 k g . As a result of the collision, the two masses stick together.

## What is an object of mass 20kg is moving with a velocity of 5m s?

The correct answer is 250 J. Given, mass (m) = 20 kg, velocity (v) = 5 ms-1. So, the kinetic energy of the object is (½)∗20∗52 = 250 J.

## What is the speed of an object of mass 10 kg that has a KE of 125j?

For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

## How to calculate velocity?

Determine the object’s original velocity by dividing the time it took for the object to travel a given distance by the total distance. In the equation V = d/t, V is the velocity, d is the distance, and t is the time.

## Does velocity mean speed?

Why is it incorrect to use the terms speed and velocity interchangeably? The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement.

## What is the formula of velocity in kinetic energy?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

## What is the velocity of a particle of mass 1kg?

The average force acting on the particle between t = 0 to t = 2s will be. Q. Velocity of a particle of mass 1 kg moving rectilinearly is given by v =25−2t+t2.

## What is the kinetic energy of an object of mass 10 kg falls from height 10 m?

E = mgh, g is acceleration due to gravity So, the kinetic energy gained by the body is 980 J.

## What is the kinetic energy gained by the body when an object of mass 10 kg falls from height 10m?

E = mgh, g is acceleration due to gravity So, the kinetic energy gained by the body is 980 J.
