What is braking force formula?

Kinetic energy is given by E = (1/2)mv^2 and Work is W = FS ; hence E = FS thus (1/2)mv^2 = FS ; Thus F = (1/2)mv^2/S. For the given values F = 0.5x 800 x 8.9^2/S = 31684/S. You have to give a value of the breaking distance to be able to find the force needed to stop the car.

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.

How much force is needed to accelerate 1000 kg car at a rate of 3m s?

hence, the force needed to accelerate the 1000kg car by 3m/s2 is 3000N .

What is average force formula?

Average Force is not a constant or absolutely measured value for velocity. It is the product of mass and average velocity during the given duration. Average Force Formula is F=m(Vf−Vi)Δt F = m ( V f − V i ) Δ t , where m is the mass, t is the time taken, and vi and vf are the initial and final velocities.

What is momentum equal to?

Momentum (P) is equal to mass (M) times velocity (v). But there are other ways to think about momentum! Force (F) is equal to the change in momentum (ΔP) over the change in time (Δt).

What is the formula for impulse using speed?

By using momentum change: The formula to calculate impulse through momentum change is by calculating the mass of the body and the velocity. In this case, Impulse will be equal to the product of mass and velocity. So J= m*v.

How much work is required to stop a car of 1000 kg with a speed of 72 km per hour?

W = 1 2 × 1000 × 20 × 20 = 400000 J.

What is the formula of 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.
