- When a net force acts on an object, it's acceleration(rate of change of speed) depend on object's shape.weight.volume.mass.initial speed.Suppose an airline allows a maximum of 45 kg for each suitcase a passenger brings along. (a) What is the weight in newtons of a 45 kg suitcase? (b) What is the weight in pounds? IbCalculate the net force acting on a 1.5 kg object that is being pushed to the right with a 3 N force across a surface with a coefficient of friction of 0.2.
- When landing after a spectacular somersault, a 30.0 kg gymnast decelerates by pushing straight down on the mat. Calculate the force (in N) she must exert if her deceleration is 7.00 times the acceleration of gravity.When you find the net force on an object, the units are always which of the following?A runner with a mass of 80 kg accelerates form 0 to 9 m/s in 3 s. Find the net force on the runner using the alternate form of Newton's 2nd law.
