Question

A student pedalling a bicycle applies a net force of 400 N. The mass of the rider and the bicycle is 25 kg. What is the acceleration of the bicycle and the rider

Answer 1

$\huge\boxed{\mathtt\green{Solution:-}}$

$\large\underline\mathtt\blue{⚘\:Given :-}$

$\small\mathtt{•\:Force=400\:N}$

$\small\mathtt{•\:Mass\:of\: the\:body=25\:kg}$

$\large\underline\mathtt\blue{⚘\:To\:Find :-}$

$\small\mathtt{•\: Acceleration\:of\:the\:body}$

$\large\underline\mathtt\blue{⚘\: Solving:-}$

$\small\mathtt{we\:know\:that:-}$

$\small\implies\mathbf{F=M×A}$

$\small\mathbf{•\:F=Force}$$\small\mathbf{•\:M=Mass}$$\small\mathbf{•\:A=acceleration}$

$\small\mathbf{Applying\: the\: Formula:-}$

$\small\implies\mathbf{400\:N=25\:kg×A}$

$\small\implies\mathbf{A=\frac{400\:N}{25\:kg}}$

$\small\mathbf{∴\:A=16\:N/kg}$

$\small\mathtt{we\:know\:that:-}$

$\small\boxed{\blue{1\:N/kg=1\:m/s²}}$

$\large\boxed{\mathtt\red{∴\: Acceleration\:of\: the\:body\:is\:16\:m/s²}}$
