two trucks are sliding a concrete block that is 8.6x10^12 kg. the first truck pushes east with a force of 58x10^9 N. the 2nd truck pushes harder with a force of 79x10^10 N. the force of friction is 14x10^3 N. what is the acceleration.
0.099m/s^2
which way do these forces act?
friction
normal
gravity
friction- parallel to the surface, opposite of the objects movement
normal- perpendicular to the surface
gravity- straight down

angle = 2.5
a golf player can hit a ball up to a speed of 68 m/s of a distance of 1.2 kilometers. its mass is 0.03 kg. determine the net force on the ball.
answer in scientific notation
8.4 x 10^-4
you are currently driving on the highway (on a 2D plane), you slow down. but according to your physics professor your acceleration was positive, explain how this is possible?
you were driving to the east so acceleration was facing towards the east, showing that you are slowing down
a 811 kg box is being pulled by a force of 861 N at an angle of 32 from the horizontal and a friction force of 400 N. What is the magnitude and direction of the normal force applied on the box?
normal force = 7491.54 N
