Racer A applies a 50 N force to a 2 kg race car. Racer B can only provide a force of 25 N.

What should the mass of Racer B's race car be in order for both race cars to accelerate at the same rate?

\[\frac{ 50N }{ 2kg } \rightarrow \frac{ 25N }{ ? }\]

Answer 7

\[\frac{ 25N }{ ? } \rightarrow \frac{ 50N }{ 2kg}\]

Answer 8

Force = mass x acceleration.
a = F/m so since the acceleration is the same
Fb/mb = FA/mA finally
mb = mA x Fb/FA = 2kg x 25N / 50N =
