In a video game, a ball moving at 0.6 meter/second collides with a wall. After the collision, the velocity of the ball changed to -0.4 meter/second. The collision takes 0.2 seconds to occur. What’s the acceleration of the ball during the collision? Use .
A.
-1.0 m/s2
B.
1.0 m/s2
C.
-5.0 m/s2
D.
5.0 m/s2
E.
0.24 m/s2

Answer:

[tex]c) -5ms^{-2}[/tex]

Explanation:

The resultant force is equal to the rate of change of momentum

Let mass =m

[tex][tex]momentum =mass*velocity\\\\Force =\frac{momentum.difference}{time}\\\\=\frac{m(0.4-0.6)}{0.2} \\=-5m[/tex]

Applying F=ma

-5m = m*a

[tex]acceleration=-5ms^{-2}[/tex]
