Answer 1

Answer:

b)f=100n

m=10kg

a=?

according to Newton's second law

f=m×a

100n=10kg×a

a=100/10=10

therefore a=10m/s^2

Answer 2

a)

Newton's second law of motion states that the rate of change of momentum is directly proportional to the applied force on an object

$\sf \mapsto f \propto \frac{ \triangle p}{t} \\ \\ \sf \mapsto f = ma$

The force that is required to accelerate a object of mass of 1 kg by 1 m/s² is called one newton

b)

Given ,

Force (f) = 100 N

Mass (m) = 10 kg

As we know that ,

f = ma

Thus ,

100 = 10 × a

a = 100/10

a = 10 m/s²

Therefore ,

The acceleration of given object is 10 m/s²
