The net force on the rocket is directed upward with a magnitude of
35 N - 25 N = 10 N
By Newton's second law, the acceleration <em>a</em> is such that net force is equal to the mass of the rocket times its acceleration:
10 N = (2.5 kg) <em>a</em>
<em>a</em> = (10 N) / (2.5 kg)
<em>a</em> = 4 m/s²
Firtly we need to know how many percents is 1/5:
1/5 * 100% = 1 * 20% = 20%
So we have 50% of party cakes and 20% of fruit cakes. Now we can easily count that sponge cakes are 30%:
100% - 50% - 20% = 30%
