What is the force applied on a body with 5kg of mass and an acceleration of 7m s2?

What is the force applied on a body with 5 kg of mass and an acceleration of 7 m/s2? Explanation: According to the second law of motion, the force on a body is equal to the rate change of its momentum. On simplifying we get, F = ma. Therefore, Force = 5 x 7 = 35 N.

How do you calculate work done by a horizontal force?

For the horizontal part, W = (50 N) * (35 m) * cos (0 deg) = 1750 J. The total work done is 3750 J (the sum of the two parts). 5. A force of 50 N acts on the block at the angle shown in the diagram.

What is the force of a 5 kg skateboard accelerating at 10m s2?

So the answer is Fnet=50N .

What is the force of a 5kg object?

The gravitational force on a body of mass 5 kg at the surface of the earth is 50 N.

How do you calculate horizontal?

Horizontal distance can be expressed as x = V * t . Vertical distance from the ground is described by the formula y = – g * t² / 2 , where g is the gravity acceleration and h is an elevation.

Which equation is used to calculate the work done on an object by a force at an angle to the displacement?

Net work is defined to be the sum of work done by all external forces—that is, net work is the work done by the net external force Fnet. In equation form, this is Wnet = Fnetd cos θ where θ is the angle between the force vector and the displacement vector.

What is the force of 5 kg?

“weight” is the force of gravity. From Newton’s laws, we have F = m*a. In the MKS system, F is in Newtons, m is the mass in kg., and a is acceleration in m/sec2 . In MKS, the a for gravity is 9.8m/sec2 and so the weight is 5*9.8 = 49 Newtons.

What is the force of friction on a body of 5kg?

A body of mass 5kg is placed on a horizontal plane. It is found that a force of 10N applied horizontally to the body is just about to move it. Calculate the coefficient of static friction between the body and the plane.

What is the work done by force of friction for 2m?

A body of mass 10 kg is moving on a horizontal surface by applying a force of 10 N in forward direction. If body moves with constant velocity, the work done by force of friction for a displacement of 2 m is : A body of mass 10 kg is moving on a horizontal surface by applying a force of 10 N in forward direction.

What is the net external force acting on a 10kg body?

A body of mass 10 kg is moving on a horizontal surface by applying a force of 10 N in forward direction. If body moves with constant velocity, the work done by force of friction for a displacement of 2 m is : As the body is moving with constant velocity, thus the net external force acting on the body must be equal to zero.

How do you calculate the force of a Newton?

F = m * a. F = 20 kg * 3 m/s 2. F = 60 N. Newtons are a derived unit, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.
