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
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.
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)!
What is an accelerating force?
An accelerating force is the force which causes accelerated motion.
If a force is exerted to the left what direction will the reaction force be exerted?
right
The force exerted on a surface divided by the area over which the force is exerted?
Pressure is the force exerted on an object divided by the area where the pressure was applied.
What is the scientific definition of force?
Pressure depends on the quantity of force exerted and the area over which the force is exerted
What is a force exerted on a surface divided by the total area over which the force is exerted?

How do you call the force exerted on a surface divided by the area over which the force is exerted?
Pressure
What kind of force is exerted on heavenly bodies?
gravitational force is exerted on heavenly bodies
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.
Picture a ball traveling at a constant speed around the inside of a circular structureis the ball accelerating?
If it's going at a constant speed then it is not accelerating. To accelerate would mean to have a rate of change for speed in some direction. If the ball is going outward while traveling at a constant speed due to centrifugal force then it is accelerating. If it's going inwards due to some ground angle then it is also accelerating. From Newton's laws we know that to have a circular motion, an object must be subject to a force directed to the centre of the structure and is accelerating in that direction. This centrifugal force, exerted by the structure to the ball, is opposite in direction and magnitude to the 'fictitious' centrifugal force.
