A dog runs at 35 m/s at 45 degrees N of E. What are its x and y components (all answers are in m/s)?

its x and y component is 24.749m/s

Explanation:

Given

Speed of the dog = 35m/s

x component of the speed = xcos theta

y component of the speed = ycos theta

Given theta =45 degrees

x-component = 35cos45

x-component = 35(0.7071)

x-component = 24.749m/s

y-component = 35sin45

y-component = 35(0.7071)

y-component = 24.749m/s

Hence its x and y component is 24.749m/s

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
