What is the net force exerted on a 90.0 kg race-car driver while the race car is accelerating from 0 to 44.7 ms in 4.50 s?
Since Force=Mass * Acceleration; and Mass= 90kg and Acceleration = (44.7 meters/second)/(4.50 sec) = 9.93 m/sec^2 Therefore, F=MA(Gc) F=(90kg)*(9.93 m/sec^2) = 893.7 kg*m/sec^2 The gravitational constant (Gc) that allows us to relate kg mass to kg force = 9.8 m/sec^2. Therefore, (893.7kg*m/sec^2) / (9.8 m/sec^2) = 91.2 kg Force

What is the mass of an object that is accelerating at 15ms when a force of 3000N is exerted?
45000 m/ s squared
What is an accelerating force?
An accelerating force is a force that causes an object to change its speed or direction of motion, resulting in acceleration. It can be exerted by various means, such as gravity, friction, or propulsion systems, and its magnitude is directly related to the object's acceleration according to Newton's second law of motion.
When you are standing on ground how much upward force exerted on you why does this force not lift u up?
The upward force exerted on you while standing on the ground is equal to your weight, as determined by the force of gravity pulling you toward the Earth. This force does not lift you up because it is balanced by the force exerted by the ground pushing back on you (normal force), keeping you in equilibrium and preventing you from accelerating upward.
Are mass and velocity forces?
No!! Force is how much work is being exerted on an object. NOT how much grav. pull (mass) or how much its accelerating (velocity)!
When you standing on the floor does the floor exert an upward force against your feet How much force does it exert?
Because your feet are not accelerating, the force exerted by the floor upon your feet must be exactly the same as the force exerted by your feet on the floor. If you are standing, the amount of force exerted by your feet, and thus the amount of force exerted by the floor, is equivalent to your weight.
What is the tension in the string as the block falls?
The tension in the string as the block falls is the force exerted by the string to support the weight of the block and keep it from accelerating too quickly.
If a force is exerted to the left what direction will the reaction force be exerted?
right
What is the meaning of Fn in force?
Fn typically denotes the normal force in physics, which is the force exerted by a surface perpendicular to an object resting on it. This force counteracts gravity and supports the weight of the object, preventing it from accelerating downward. The normal force can vary depending on the angle of the surface and other forces acting on the object.
What two forces are of central concern to racecar designers?
Down force and lateral force.
What is gravitational force exerted on an object called?
The gravitational force exerted on an object is called weight. It is the force exerted by gravity on the object's mass.
What is output force - Output force is the force exerted on an object by a simple machine?
Answer: Output force is the force exerted on an object by a simple machine.
What is a force exerted on a surface divided by the total area over which the force is exerted?
cheeseburger
