PLEASE HELP: Use Newton’s second law of motion to determine the unknown values for the following objects in motion. Assume all objects are being accelerated on frictionless surfaces or through frictionless mediums. Calculate the values, and round your answer to the correct number of significant digits. If needed, use the conversion factor 1 lb = .454 kg.


Baseball data: 0.142 kg, 1._________N, 388 m/s2

Football player data: 0.426 m/s2 , 2._________kg, 28.39 N of force pushing the player over the goal line, and 1.98 N of force by defender pushing in the opposite direction

Wagon data: 77.6 lbs,128 N, 3.___________m/s2

Answer :

The force exerted by Baseball is 55.01 N.

The mass of the Football player is 62.0 Kg.

The acceleration of the Wagon is 3.63 m/s².

What is force?

Force is the influence that can change the state of the body of rest or motion. Force is a vector quantity and the SI unit of force is Newton. Force can change the direction and speed of the moving object.

The force can be determined by the product of the mass (m) and acceleration (a). The mathematical expression from the second law of motion for force can be written as:

F = ma

Given, the mass of the baseball is 0.142 Kg and the acceleration of the baseball is 388 m/s2.

The force exerted by the baseball, F = ma = 0.142 Kg × 388 m/s2

F = 55.096 N

F = 55.01 N

Given, the acceleration of the football player, a = 0.426 m/s2

The net force = 28.39 - 1.98 = 26.41 N

The mass of football player, m = F/a = 26.41/0.426 = 61.99 = 62.0 Kg

The force of the wagon, F = 128 N

The mass of the wagon = 77.6 Ibs = 77.6 × 0.454 Kg = 35.23 Kg

The acceleration of the wagon = 128/ 35.23 = 3.63 m/s²
