A body of mass 20 kg is kept in equilibrium of two forces. If one of the ropes pull the body in a horizontal direction and the other in a direction of 60 degree with the vertical, calculate the tension in each rope.

A car is moving 14.4 m/s when it hits the brakes. It slows for 78.8 m, which takes 9.92 s. It then accelerates at 1.83 m/s^2 for 4.50 s. What is its final velocity? 2-part motion 1-D kinematics

When the resistance in a circuit remains constant, how are the voltage and current related? 1) The current doubles when the voltage doubles because they are directly proportional.
