Answer:
The position is relative to the base of the ocean
Explanation:
From the question we are told that
The angle made by the incline with the horizontal is
The constant acceleration is
The distance covered is
The height of the cliff is
The velocity of the car is mathematically represented as
The initial velocity of the car is u= 0
So
substituting values
The vertical component of this velocity is
substituting values
The negative sign is because is moving in the negative direction of the y-axis
The horizontal component of this velocity is
Now according to equation of motion we have
substituting values
using quadratic equation we have that
given that time cannot be negative
The car’s position relative to the base of the cliff when the car lands in the ocean is mathematically evaluate as
substituting values
Answer:
e telescopes

One year it just feels like less because you’re going so fast
For the heart rate :
n = number of heat beats = 36
t = time taken to measure = 30 s = 30/60 min = 0.5 min (since 1 min = 60 sec)
R = heart rate
Heart rate is given as
inserting the values
R = 72 min⁻¹
For uncertainty :
Δn = uncertainty in number of heat beats = ± 2
Δt = uncertainty in time taken = ± 0.4 s = ± 0.4/60 min = ± 0.0067 min (since 1 min = 60 sec)
ΔR = uncertainty in heart rate
uncertainty in Heart rate is given as
inserting the values
ΔR = ± 4.96 min⁻¹
