How much force, in g cm/s2
, is exerted by a golf ball of 50 g striking a tree while accelerating
at 20 cm / s2
? Show how you can solve this problem without knowing Newton’s second law.
Explain your solution

in this question force is measured in  g cm/s2 so we know that to get the answer we times g by cm/s2 
50 × 20 = 1000

Answer:

[tex]F=1000\frac{gr \times cm}{s^{2} }[/tex]

Explanation:

Givens

[tex]m=50g[/tex]

[tex]a=20cm/s^{2}[/tex]

To find the force exerted by the golf ball, we need to use Netwon's second law, which is defined as

[tex]F=ma[/tex]

In words, when we apply a force to an object with mass [tex]m[/tex], the object will accelerate at [tex]a[/tex].

Now, replacing all given values, we have

[tex]F=ma\\F=50g(20cm/s^{2} )\\F=1000\frac{gr \times cm}{s^{2} }[/tex]

Therefore, the force exerted by the golf ball is [tex]F=1000\frac{gr \times cm}{s^{2} }[/tex]
