. On a safari, a team of naturalists sets out toward a research station located 9.6 km away in a direction 42° north of east. Af

Elden [556K]

Answer: $\theta =49.76^{\circ}$ North of east

Explanation:

Given

Research station is 9.6 km away in $42^{\circ}$ North of east

after travelling 3.1 km $25^{\circ}$ north of east

Position vector of safari after 3.1 km is

$r_2=3.1cos25\hat{i}+3.1sin25\hat{j}$

Position vector if had traveled correctly is

$r_0=9.6cos42\hat{i}+9.6sin42\hat{j}$

Now applying triangle law of vector addition we can get the required vector $(r_1)$

$r_1+r_2=r_0$

$r_1=(9.6cos42-3.1cos25)\hat{i}+(9.6sin42-3.1sin25)\hat{j}$

$r_1=4.325\hat{i}+5.112\hat{j}$

Direction is given by

$tan\theta =\frac{y}{x}=\frac{5.112}{4.325}$

$\theta =49.76^{\circ}$

Q1: Using the known values of the mass of the earth and the radius of the earth, calculate the

kupik [55]

Answer:

m g = G * m * M / R^2 force of attraction

g = G * M / R^2

g = 6.67E-11 * 5.96E24 / (6.37E6)^2

g = 6.67 * 5.96 / 6.37^2 * 10^1

g = .98 * 10 = 9.8 m/s^2

Q2.

d g = G M * (-2 R^-3 dR ) = -2 G M / R^3 (very small where dR = 1)
