Question

Chapter 04, Problem 012 At an instant when a soccer ball is in contact with the foot of the player kicking it, the horizontal or x component of the ball's acceleration is 810 m/s^2 and the vertical or y component of its acceleration is 950 m/s^2. The ball's mass is 0.47 kg. What is the magnitude of the net force acting on the soccer ball at this instant? Number [ ] Units the tolerance is +/-1 in the 2nd significant digit By accessing this Question Assistance, you will learn while you earn points based on the Point Potential Policy set by your instructor.

Explanation / Answer

a net = sqrt(ax^2 + ay^2) = sqrt(810^2 + 950^2)

F = m anet = 0.47*sqrt(810^2 + 950^2)=586.8 N
