Answer:
(472i + 80.3j) m
Explanation:
Given the following :
Distance of tee shot = 300m
Distance of second shot = 189.0 m
Displacement r1 of tee shot :
r1 = 300 mi
Displacement r2 of second shot :
r2 = 172.0 mi + 80.3 mj
The final displacement of the golf ball from the tee:
r_final = r1 + r2
r_final = (300i)m + (172.0i + 80.3j) m
r_final = (300 + 172)i m + 80.3j m
r_final = (472i + 80.3j) m
Yes. Everybody on Earth sees the same moon phase at the same time.
Explanation:
Let acceleration due to Gravity for a planet is given by:

Here,
Escape velocity is given by:

Here,
and g_X = 2g
Therefore,
Answer:

Explanation:
= Mass of the Earth = 5.972 × 10²⁴ kg
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
r = Radius of Earth = 6371000 m
m = Mass of person
The force on the person will balance the gravitational force

The acceleration that the Earth will feel is 
use consevation of linear momentum
- m1v1+m2v2=(M1+M2)V3
- 281(2.82)+209(-1.72)=(209+281)V2
- 792.42-359.48=490v3
- 432.9=490v3
- V3=0.88m/s
