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 answer would be 80kg/ms or 80N because:
force= mass x acceleration
= 20kg x 4ms
=80kg/ms
=80N

a force lil' G !!

How do you calculate braking torque?
To calculate brake torque, multiply force with the distance from the point of rotation. Force is equal to the torsional reaction caused by the brakes, and is also equal in magnitude to the torque exerted by the road.
What is the force exerted upwards from the ground?
In mechanics, the force exerted upwards by the surface that a body sits on is equal and opposite to the force exerted downwards by that body and is referred to as the Ground Reaction Force (GRF) or simply Reaction.

When a force on an object increases how does the object acceleration change?
Changing the magnitude or direction of forces exerted on an object changes the net force (sum of all forces) exerted on the object. The net force exerted on an object is defined as mass times acceleration (F = ma), where mass, m, is constant. This means that when the net force exerted on the object changes in magnitude (or direction), its acceleration will also change in magnitude (or direction). In addition, acceleration is defined as the change in velocity, so when the magnitude (or direction) of acceleration changes, the magnitude (or direction) of velocity will also change.
In which direction is pressure exerted in a fluid at rest?
If its in a container, pressure is downward and outward due to gravity and confinement respectively. If its on a flat surface without confinement, the pressure is exerted downwards on the surface and the boundaries are held by a combination of adhesion and cohesion.
If a crate accelerates at 2.5 m5 and if the net force exerted is about 500N what is the mass of the crate?
In accordance to Newton's Second Law, you need to divide the force by the acceleration. The answer in this case will be in kilograms.

The force that accelerates a car on a level road is exerted by which object?
In short: the tires. (friction) The force changes a few times to get there though. (gasoline -> chemical reaction -> pressure -> linear kinetic -> rotational kinetic)
What kind of newtons law of motion is illustrated if the force that accelerates a rocket into outer space is exerted on the rocket by the exhaust gases?
For every action, there is an equal and opposite reaction (Newton's third law of motion)..
