... If a 861.5 kg car goes from rest to 35.8 m/s in 2.94 s, what is the acceleration on the car, and what net force is propelling it? If a 3.8 kg ball is pushed horizontally across a frictionless surface from rest with a force of 65.8 N until it attains a speed of 15.8 m/s, how far did you push it? A 12 ...

... A person's sensation of weight is due to the presence of a normal force upon their body. Usually, this normal force is of the same magnitude as the force of gravity. So a 600 Newton person typically feels 600 N of normal force to provide a sensation of how much they weigh. When the normal force beco ...
