Answer 1

Answer:

force = 0.4 N

Step-by-step explanation:

acceleration a

$a = \frac{20 - 0}{5 - 0} \\ \\ = 20 \div 5 \\ \\ = 4 \: \: m {s}^{ - 1} \\ \\ \\ therefore \: \: \: \: required \: \: \: \: f = m \times a \\ = \frac{100}{1000} \times 4 \\ \\ = \frac{4}{10} \\ \\ f \: \: \: = \: \: \: 0.4 \: \: \: newton$
