M=3000km v=25m/s what’s the momentum

valina [46]

<h3>Answer:</h3>

Momentum of the given body will be : 75000 Kg m/s

<h3>Explanation:</h3>

According to Newton's first law of motion, all bodies continue to be in the state of rest or motion unless an external force is applied on the body. We can use this in the case of momentum also

The formula of momentum is given by :

$:\implies \sf\quad \sf \: P = mv$

Here, we are given the mass of the body ( m ) as 3000kg and the velocity of the body ( v ) as 25 m/s. On putting the values in the formula:

$\begin{aligned}&:\implies \sf\quad \sf \: P = mv \\& :\implies \sf\quad \sf \: P = 3000 \times 25 \\ & :\implies \sf\quad \sf \: \boxed{ \sf \: P = 75000kgm {s}^{ - 1} } \end{aligned}$

Momentum is associated with the mass of the moving body and can be defined as the quantity of motion measured as a product of mass and velocity.

What speed would a proton need to achieve in order to circle Earth 1790 km above the magnetic equator, where the Earth's mag- ne

irinina [24]

Answer:

The velocity is 31.25 m/s and direction is toward west.

Explanation:

Given that,

Distance $h= 1790 km = 1.790\times10^{6}\ m$

Magnetic field $B=4\times10^{-8}\ T$

Mass of proton $m=1.673\times10^{-21}\ Kg$

Radius of earth $R =6.38\times10^{6}\ m$

Radius of orbit $r=R+h$

$r=6.38\times10^{6}+1.790\times10^{6}$

$r=8170000\ m$

We need to calculate the speed

Using formula of magnetic field

$Bvq=\dfrac{mv^2}{r}$

$v=\dfrac{Bqr}{m}$

Put the value into the formula

$v=\dfrac{4\times10^{-8}\times1.6\times10^{-19}\times8170000}{1.673\times10^{-21}}$

$v=31.25\ m/s$

Hence, The velocity is 31.25 m/s and direction is toward west.

$\sf \huge \purple{ Question : - }$

Initial velocity of a car is 36 km/h . Find the distance after min, if it goes with acceleration 2 m/s².

$\sf \huge \color {gold}{ AnSwer :- }$

Initial velocity, u = 36 km/h

$\sf u = 36 \times \dfrac{5}{18} {ms}^{ - 1} = 10 {ms}^{ - 1}$

Time, t = 1min

t = 60s

Acceleration, a = 2m/s²

Apply 2nd equation of motion

$\longrightarrow \sf s = ut + \dfrac{1}{2} at ^{2} \\ \\ \longrightarrow \sf s =(10)(60) + \frac{1}{2} (2)(60) {}^{2} \\ \\ \longrightarrow \sf s =600 + 3600 \\ \\ \longrightarrow \sf \blue{ s =4200m} \: \: \large \blue \star$
