science help (newton's second law of motion) more questions?
Carlo and Sara push on a desk in the same direction. Carlo pushes with a force of 50N, and Sara pusheswith a force of 40N. Ehat is the total resultantforce acting on the ball?
A car is stuck in the mud. Four adults each push on the back of the car with a force of 200N. What is the total force on the car?
In auto racing, a cruash occurs. A red car hits a blue car from the front with a force of 4000N. A yellow car also hits the blue car from the side with a force of 5000N. What is the total force on the blue car? (Since force is a vector, you must give both the magnitude and direction of the force.)
If the acceleration due to gravity at the surface of the Earth is approximately 9.8 m/s^2, what force does the gravitational attraction of the Earth exert on a 12.8-kg object?
If Carlo and Sara are pushing on the desk, not the ball. The force on the ball is 0.
4 x 200N = 800N
Take the square root of the sum of the squares. sqr root of (4000^2+5000^2). The direction is simple trig. Tan A = opp/adj
Trick question. The force is the same on any weight.
