Question

find ...................... ?​

Answer 1

Given :

• Acceleration ( a ) = 5 km / hr²

To Find :

• Acceleration in CGS unit

Solution :

• In CGS system the distance is measured in Centimetre and time is measured in second
• Unit of acceleration in CGS system is cm / s²

$\tt1 \: km = 1 \times {10}^{5} \: cm \\ \\ \tt5 \: km = 5 \times {10}^{5} \: cm \\ \\ \tt 1 hr = 3.6 \times{10}^{3} \:sec \\ \\ \tt a = \dfrac{5 \times {10}^{5} }{3.6 \times {10}^{3} } \\ \\ \tt a = \frac{5 \times {10}^{2} }{3.6} \\ \\ \tt a = 138.88 \: cm \: {s}^{ - 2} \\ \\ \underline{\tt \green{ Acceleration \: of \: body \: is \: 138.88 \: cm \: {s}^{ - 2}}}$
