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

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).

## What is a 2 kg object moving at a speed of 3.0 m s collides with?

Final answer: Using the principle of conservation of momentum, we find that after the 2 kg object moving at 3.0 m/s collides with a 1 kg object at rest, the combined object moves at 2.0 m/s in the same direction as the original moving object.

## 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 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 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 law of moving a body of mass 2kg?

A body of mass 2kg travels according to the law x(t) = pt + qt^(2) + r… Displacement (y) of a body is represented by y = pt + qt^(2) – rt^(3)… Displacement (y) of a body is represented by y = pt + qt^(2) – rt^(3)… A body of mass 2 kg is moving according to the equation for displaceme…

## What is the formula for velocity of a collision?

What is the formula of collision? From the conservation of momentum, the formula during a collision is given by: m1v1 + m2v2 = m1v’1 + m2v’2. If the collision is perfectly inelastic, the final velocity of the system is determined using v’ = (m1v1 + m2v2)/m1 + m2.

## What is the formula for the velocity of a particle after a collision?

If two particles are involved in an elastic collision, the velocity of the second particle after collision can be expressed as: v2f=2⋅m1(m2+m1)v1i+(m2−m1)(m2+m1)v2i.

## What happens when two objects of equal mass and velocity collide?

When two objects with the same mass collide, Newton’s laws tell us that they will accelerate the same amount but in opposite directions. Recall that force, velocity, and acceleration have both magnitude and direction. We use positive and negative signs to indicate the direction of each of these quantities.

## 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 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 are the velocities of two bodies masses 5 kg and 10 kg?

As the total mass is (5+10)=15kg, hence the speed= the magnitude of the velocity = 20√2/15 = 4√2/3 ~ 1.9m/s. The velocity vector is (4√2/3)(i+j)/√2 = (4/3)(i+j).

## What is the moment of inertia of a body is 2.5 kg?

The moment of inertia of a body is 2.5 kg metre square calculate the torque required to produce an angular acceleration of 18 Radian per second square in the body. a = 18 rad/sec square. T = ? = 2.5 * 18 = 45 N.

## What is the velocity of a body of mass 2kg changes from?

The velocity of a body of mass 2 kg changes from v1= 2ˆi+3ˆj−ˆk m/s to v2=−3ˆi+2ˆj+3 ˆk m/s in 3 sec under the influence of a external force.
