Answer:
1500 mph
Explanation:
Take east to be +x and north to be +y.
The x component of the velocity is:
vₓ = 889 cos 0° + 830 cos 59°
vₓ = 1316.5 mph
The y component of the velocity is:
vᵧ = 889 sin 0° + 830 sin 59°
vᵧ = 711.4 mph
The speed is found with Pythagorean theorem:
v² = vₓ² + vᵧ²
v² = (1316.5 mph)² + (711.4 mph)²
v = 1496 mph
Rounded to two significant figures, the jet's speed relative to the ground is 1500 mph.

Science may also be defined as the study of surroundings
Answer:
Afforestation is the planting or adding of trees in an area where there was never a forest or plantation. This is a method to create a new forest. Reforestation is the replanting of trees in an area where there was once a forest which was destroyed or damaged.
Explanation:
Answer:
F = M a = M v^2 / R
If v is increased by three the force will be increased by nine,
C) is correct
Answer: 30 Newton
Explanation:
Force can be obtained from the product of Mass M and acceleration A. The SI unit of force is Newton.
Thus, Force = MA
Mass of the arrow = 2kg
Acceleration of the arrow = 15m/s2
Force = 2kg x 15m/s2
Force = 30 Newton
Thus, the hunter require a force of 30 newton
