Question

Calculate the magnitude of the linear momentum for the following cases. (a) a proton with mass 1.67 10-27 kg, moving with a speed of 4.85 106 m/s

Answer 1

8.0995×10^-21 kgms^-1

Step-by-step explanation:

Mass of proton :

`m_P=1.67* 10^-^2^7\:kg\\`

Speed of Proton:

`v_P=4.85* 10^6`

Linear Momentum of a particle having mass (m) and velocity (v) :

`-> p =m->v\:\:\: (1)`

Magnitude of momentum :

`p=mv\:\:\: (2)`

Frome equation (2), magnitude of linear momentum of the proton :

`p_P=m_P\:v_P\\\\p_P=1.67* 10^-^2^7 \:kg*4.85* 10^6\:ms^-^1\\\\p_P= 8.0995* 10^-^2^1\:kgms^-^1`
