Answer:

The total displacement is 102 km $51^o$ north of east.

Explanation:

We can treat this problem as a trigonometric one, so we need to calculate the total displacement on the north and east.

$d_n=34km+79km*sin(35^o)=79km$

and

$d_e=79*cos(35^o)=65km$

The total displacement is given by:

$D=\sqrt{(79km)^2+(65km)^2}=102km$

with an agle of:

$\alpha =arctg(\frac{79km}{65km})=51^o$

Rank in terms of momentum

eduard

Answer:

See the explanation below,

Explanation:

Momentum is defined as the product of mass by Velocity. In this way, we will replace the following equation in each of the cases.

$P=m*v$

where:

P = momentum [kg*m/s]

m = mass [kg]

v = velocity [m/s]

$P = 10000*0\\P=0$

$P=100*5\\P=500[kg*m/s]$

$P=1200*15\\P=18000[kg*m/s]$

$P=15*1000\\P=15000[kg*m/s]$

From higher to lower momentum

Is distance a vector quantity

fgiga [73]

Explanation:

Nope, displacement is a vector quantity, whereas distance is the scalar (magnitude) of the total displacement.

Hope this clears things up :))
