## 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 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 kinetic energy of 2kg 10m s?

The correct answer is 100 J. We know that when the ball reaches the highest point, its whole kinetic energy is converted into Potential energy.

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

The kinetic energy of the object is 125 J.

## What is the speed of an object of 1 kg mass with a kinetic energy of 50 J?

Mass (m)= 1 kg. Velocity (v)= 10 m/s. ∴The Kinetic Energy of the object is 50 J. ∴ The correct option is the 4th.

## What’s the formula for 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 kinetic energy of a 2kg ball dropped from a height of 10m?

Now, By the law of the conservation of the Energy, Total amount of the energy of the system remains constant. ∴ Kinetic Energy before the body reaches the ground is equal to the Potential Energy at the height of 10 m. ∴ Kinetic Energy = 980 J.

## What is the velocity of a body of mass 2kg moving in the xy plane?

Velocity of a body of mass 2 kg moving in x-y plane is given by v⃗ =(2i^+4tj^)m/s, where t is the time in second.

## What is the formula for kinetic energy Grade 10?

The kinetic energy formula means: 1/2 multiplied by the mass multiplied by velocity squared. You don’t multiply half of the mass with half of the velocity squared because that would give you 1/4mv^2 instead.

## What is a mass of 10 kg moves with velocity of 4m s?

Answer and Explanation: K = 1 2 m v 2 = 1 2 ( 10 kg ) ( 4 m/s ) 2 = 80 J .

## What is a mass of 10kg moves with a velocity of 4m?

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 is the acceleration of an object with a mass of 10 kg and a net force of 30 N?

By taking the formula F=m*a, and rearranging the make a the subject, we get a=F/m. Then by substituting in the values given we can work out that a=30/10=3. The units of acceleration are ms-2 so hence, the object will accelerate at 3ms-2.
