Question

at an instant when a soccer ball is in contact with the foot of a player kicking it, the horizontal or x component of the ball’s acceleration is 810 m/s2 and the vertical or y component of its acceleration is 1100 m/s2 . the ball’s mass is 0.43 kg. what is the magnitude of the net force acting on the soccer ball at this instant

Answer 1

487.13N

Step-by-step explanation:

According to Newton's second law;

F = ma

F is the net force

m is the mass of the object

a is the acceleration

First we need to find the resultant of the acceleration

a =√810²+910²

a = √656,100+828,100

a =√1,484,200

a = 1218.28m/s²

Ball mass = 0.40kg

Next is to get the magnitude of the net force

F = 0.4 × 1218.28

F = 487.31N

Hence the magnitude of the net force acting on the soccer ball at this instant is 487.13N
