Rabbit's position vector (r) in the unit vector is 203.5î - 57j and the magnitude and directional angle of vector (r) are 195.35m and 0.004° respectively.
Given
x = 0.3t² + 7.2t + 28
y = 0.22t² - 9.1t +30
At t = 15s
x = 0.3(15)² + 7.2(15) +28 = 203.5
y = 0.22(15)² - 9.1(15) + 30 = -57
The rabbit's position vector (r) in unit vector notation is:
r = 203.5î - 57j
The magnitude of position vector (r)
r = √x² + y²
r = √(203.5)² - (57)² =√38163.25
= 195.35m
The directional angle of position vector (r)
tanθ = y/x = -57/203.5
θ = 
(-57/203.5)
θ = 0.004°
Hence, rabbit's position vector (r) in the unit vector is 203.5î - 57j and the magnitude and directional angle of vector (r) are 195.35m and 0.004° respectively.

D. Elevate the affected area.
The therapy measures for musculoskeletal injuries may be remembered by using the acronym RICE, which stands for Rest, Ice, Compression, and Elevation. Muscle, nerve, tendon, joint, cartilage, and spinal disc injuries and diseases are referred to as musculoskeletal disorders (MSD).
Rest encourages recovery and helps to stop further harm. During the first 24-48 hours following an accident, intermittently applying moist or dry cold packs for 20–30 minutes causes vasoconstriction, which lessens bleeding, edema, and pain.
Take precautions to prevent tissue and skin damage from extreme cold. An elastic compression bandage supports the wounded tissues while controlling bleeding and edema. Swelling is controlled by elevation.
