Answer:
V = (Vx^2 + Vy^2)^1/2 = (40^2 + 62^2)^1/2
V = 73.8 m/s
tan theta = Vy / Vx = 62/40 = 1.55
theta = 57.2 deg
Opposite charges attract
Like charges repel
Explanation:
Below is an attachment containing the solution.
Use this numbers that you are given and plug them into the formule for net force
Net force= m*a (mass times acceleration)
Therefore the net force is equal to (5.5 kg)*(4.2 m/s^2)= 23.1 N
Answer: Net force= 23.1 N
It would take 5.0 s for a racehorse to accelerate from rest to a speed of 15 m/s with an acceleration of 3.0 m/s.
Take 15 / 3.0 to get your answer of D. 5.0 s
Hope that helps u out!
