Answer:
magnitude = 7.446 km, direction = 75.22° north of east
Explanation:
From the questions,
To get the the magnitude of the resultant vector we use Pythagoras theorem
a² = b²+c²
From the diagram,
y² = 1.9²+7.2²
y² = 55.45
y = √(55.45)
y = 7.446 km.
The direction of the dolphin is given as,
θ = tan⁻¹(7.2/1.9)
θ = tan⁻¹(3.7895)
θ = 75.22° north of east
Hence the magnitude of the resultant vector = 7.446 km, and it direction is 75.22° north of east
Answer:
1 inch = 2.54 cm
12.9 inches= 12.9 x 2.54
= 32.766
= 32.8 cm (approximately)

D. potential energy, because there is a bunch of water pent up, essentially stationary, waiting to roll down the steep mountain from the peak, so to say. if the dam were to be removed it would become kinetic.
A. The average speed is
<span>12 km/18 min = 0.67 km/min
b. The average velocity is
10.3 km/18 min = 0.57 km/min
c. average speed is 24 km/450 min = 0.05 km/min
average velocity = 0 since the displacement is 0.

Answer:
<em>The tiger will land at 3.71 meters from the base of the rock</em>
Explanation:
<u>Horizontal Motion</u>
When an object is thrown horizontally with a speed vo from a height h, the range or maximum horizontal distance traveled by the object can be calculated as follows:
The tiger leaps from a height of h=7.5 m with a speed of v=3 m/s. Substituting the values into the formula:
The tiger will land at 3.71 meters from the base of the rock
