A = k/R where A = acceleration and R = radius of the turn and k is a constant to be found.
Substituting the given values:-
10 = k / 70
k = 10*70 = 700
So the equation of the motion is A = 700 / R
When the radius is 140 the acceleration is 700 / 140 = 5 ft/sec/sec ( answer)
Answer:
Bottom right
First you multiply the bottom (2.5 x 1.5) to get 3.75. Then multiply 3.75 by 2 to got 7.5.
Whole equation: (2.5 x 1.5) x 2.0 = 7.5
The sides of the triangle are 3x, 4x and 5x
3x + 4x + 5x = 90
12x = 90
x = 90/12
x = 7.5
first side = 3x = 3 * 7.5 = 22.5 cm
second side = 4x = 4 * 7.5 = 30 cm
third side = 5x = 5*7.5 = 37.5 cm
The answer is 1432 x 54 = 77,328
