A. statement of fact meant to explain an action
Answer:
E = 1/2 m v^2 = 1/2 k x^2 equating KE of coyote and spring
x^2 = m v^2 / k = 10 kg * 20^2 m^2 / s^2 / 400 N / m
x^2 = 10 * 400 / 400 (kg m^3 / kg-m) = 10 m^2
x = 3.16 m
Explanation:
the speed of the motor can be increased by increasing the strength magnetic field increasing the current flowing through the coil.
