# What is a body of mass 2 kg moves with an acceleration 3m?

## What is a body of mass 2 kg moves with an acceleration 3m?

Answer: the force acting on the body with a mass of 2 kg and an acceleration of 3 m/s² is 6 Newtons (N). Where: F is the force in Newtons (N).

## How much work is done on a body of mass 2 kg moving in a circular path of radius 2m?

So, work done will be 0.

## 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 a block of mass 2 kg moving with?

A block of mass 2 kg is moving with speed v0 towards a massless unstreched spring (K=10N/m). It is found that for maximum speed v0=√6.4m/s, the block compresses the spring, stops at that position and does not return back. Friction coefficient at surface is μ=1x.

## How much force is required to accelerate a 2 kg mass at 3m s?

Force (F)= Mass (m)× Acceleration (a). ∴F=ma. ∴F=(2kg)×(3ms2). ∴F=6kgms2=6 Newton.

## What is the formula of change in momentum?

Step 1: Identify the mass of the object, , the initial velocity of the object, , and the final velocity of the object, . Step 2: Calculate the change in momentum, which is equal to the impulse, , using the formula Δ p = m ( v f − v i ) .

## What is the formula for mass work?

Work is the force exerted on an object times the distance over which the force is exerted: W = Fx, where W is the work in Nm = Joule. Work done to lift an object of mass m a height h: W = Fgh = mgh. Work done against friction: W = Ff x.

## What is the formula for work done in circular motion?

We know W=F.S or F. Scos(θ), since body is moving in circular track cos(θ)=0 , and hence whole term will be 0 i.e. Work done will be 0.

## What is the formula for work done in a moving body?

For a given amount of force, F, and a given distance, d, the work done on an object is given by the formula W = F ⋅ d . Note that this formula assumes that the force is applied in a direction parallel to the direction of motion of the object.

## 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 solid mass 2 kg moving with velocity 10 ms?

A solid of mass 2 kg moving with velocity 10 m/s strikes an ideal weightless spring and produces a compression of 25 cm in it. Calculate the force- constant of the spring. Ans. 3200 N/m.

## 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 5 kg mass?

Answer: Thus, the acceleration of 5kg mass is 5. 44m/s2.

## What is the formula for the mass of a moving object?

As the object approaches the speed of light, the object’s energy and momentum increase without bound. Tolman in 1912 further elaborated on this concept, and stated: the expression m0(1 − v2/c2)−1/2 is best suited for the mass of a moving body.

## What is the formula for moving mass and rest mass?

Thus, the correct formula is m=m0√1−v2c2. Was this answer helpful? A famous relation in physics relates moving mass m to the rest mass m0 of a particle in terms of its speed v and the speed of light c. (This relation first arose as a consequence of special theory of relatively given by Albert Einstein).

## How much work is done on a body of mass 1 kg moving on a circular path of radius 5 m?

Answer: work done on a body of mass 1 kg whirling on a circular path of radius 5m is zero, because the direction of the displacement is in the direction of the tangent drawn at the position of the body of 1 kg mass to circle of the path of the motion and the force acting on the body to move it in the circular motion in …

## What is the amount of work done to raise an object of mass 2 kg to a height of 10 m?

Hence, the Work done to life the mass of 2 kg to a height of 10 m is 196 J.

## How much work is done on a body moving on a circular path?

The work done on a body moving in a circular path is also zero. This is because, when a body moves in a circular path, then the centripetal force acts along the radius of the circle, and it is at right angles to the motion of the body. Thus, the work done in the case of moon moving round the earth is also zero.

=2×10×50=1000J.
