To determine the time for a body to acquire a velocity of 100 m/s under a constant force of 100 N, you can use the equation ( F = ma ). Rearranging it to solve for acceleration ( a = F/m ), the acceleration will be ( 100 N / 20 kg = 5 m/s^2 ). Then, using the equation ( v = at ), where ( v = 100 m/s ) and ( a = 5 m/s^2 ), you can solve for ( t ) (time), which becomes ( t = v/a = 100 m/s / 5 m/s^2 = 20 s ). Therefore, the force should act for 20 seconds.

How much force is needed to hold up a 20kg bag of sand?

The force needed to hold up a 20kg bag of sand would be equivalent to the weight of the bag, which is approximately 196 Newtons (N) on Earth.


What force is required to hold up an object of mass 20kg?

The force required to hold up an object of mass 20kg is equal to its weight, which is 20kg multiplied by the acceleration due to gravity (around 9.8 m/s^2). Therefore, the force required is approximately 196 newtons.


How much force would it take to lift a 20kg object on earth?

The force required to lift a 20kg object on Earth would be equivalent to the object's weight. On Earth, the force of gravity is approximately 9.81 m/s^2, so the force needed to lift a 20kg object would be 20kg * 9.81 m/s^2 = 196.2 N.


If an object with a mass of 20kg is lying on the floor of a lift and the lift accelerates downwards at 4ms calculate the magnitude of the force exerted by the floor of the lift on the object?

The force exerted by the floor of the lift on the object will be the sum of the gravitational force acting downwards and the force necessary to accelerate the object downwards with the lift. The magnitude of the force will be the sum of the object's weight (mg) and the force due to acceleration (ma), which equals (20kg * 9.81 m/s^2) + (20kg * 4 m/s^2) = 196.2N + 80N = 276.2N.


Is 20kg of lead heavier than 20kg of feather in vacuum?

No, 20kg of lead and 20kg of feathers would have the same mass in vacuum since both are 20kg. Gravity does not affect mass.

What is the gravitational force between a mass of 20kg and a mass of 100kg that are 15 meters apart?

The gravitational force between the 20kg mass and the 100kg mass that are 15 meters apart can be calculated using the formula for gravitational force: F = G * (m1 * m2) / r^2, where G is the gravitational constant (6.67 x 10^-11 N m^2/kg^2), m1 and m2 are the masses (20kg and 100kg), and r is the distance (15 meters). Plugging in the values gives us F = 1.78 x 10^-8 Newtons.


How much is 20kg in g?

20kg is equal to 20,000g.


Is 20kg lead in a vacuum heavier than 20kg feather in a vacuum?

No. Weight = mass x gravity, so for the same mass, you get the same weight.


How much force is required to accelerate a 10kg bicycle along with it's 10kg?

To accelerate a 20kg bicycle (10kg bike + 10kg rider) at a rate of 2 m/s^2, you would need a force of 40 newtons. This is calculated by multiplying the mass (20kg) by the acceleration (2 m/s^2).
