Answer:
The question is incomplete, the complete question is "A car drives on a circular road of radius R. The distance driven by the car is given by d(t)= at^3+bt [where a and b are constants, and t in seconds will give d in meters]. In terms of a, b, and R, and when t = 3 seconds, find an expression for the magnitudes of (i) the tangential acceleration aTAN, and (ii) the radial acceleration aRAD3"
answers:
a.
b.
Explanation:
First let state the mathematical expression for the tangential acceleration and the radial acceleration.
a. tangential acceleration is express as
since the distance is expressed as
the derivative is the velocity, hence
hence when we take the drivative of the velocity we arrive at
b. the expression for the radial acceleration is expressed as
Speed= f x λ ( f= frequency. λ = wavelength)
Speed = 2Hz x 6m
= 12m/s
Answer:
23 m/s
Explanation:
First, find the time it takes for the car to fall 40 meters.
y = y₀ + v₀ t + ½ at²
0 = 40 + (0) t + ½ (-9.8) t²
0 = 40 − 4.9 t²
t = 2.89 s
Next, find the velocity needed to travel 65 meters in that time.
x = x₀ + v₀ t + ½ at²
65 = 0 + v₀ (2.89) + ½ (0) (2.89)²
v₀ = 22.75 m/s
Rounding to two significant figures, the car's initial speed was 23 m/s.
Explanation:
Given that,
Let ABC is a triangle such that AB is perpendicular distance, BC is base and AC is the hypotenuse of triangle.
Let AB = 210 ft
AC = 90 + x
BC = x
To find :
The dimensions of the cornfield.
Solution :
Pythagoras theorem is used to find the value of x. It is given by :
On solving the above equation we find the value of x, x = 200 ft
So, BC = 200 ft
AC = 90 + 200 = 290 ft
So, the length, base and the hypotenuse of the triangle is 210 ft, 200 ft and 290 ft respectively.
