Phys 202A Homework 7 Solutions 7. Since point P lies directly
... Their sum is zero. Note that the +3.0q charge and the –12q charge produce electric fields at P in opposite directions. The –12q charge has a magnitude four times that of the +3.0q charge but is twice as far away. Since E q r 2 , the forces due to these two charges also sum to zero. So the net field ...

... Choosing coordinates well is important A tennis ball is hit at 50 mps at an angle of 5 degrees above the horizontal. The initial height is 2 m. Neglecting air drag, how far does the ball go before hitting the ground? Choose +x to be in the direction the ball starts at. Choose +y to be at right angle ...

Newton`s 2nd Law
... • Zoo keepers lift a stretcher that holds a sedated lion. The total mass of the lion and stretcher is 175 kg, and the upward acceleration of the lion and stretcher is 0.657 m/s2. What force is needed to produce this acceleration of the lion and the stretcher? • Known: m = 175 kg Equation: F=ma a = 0 ...

... 1. Use Newton’s first law to explain why packages in the back of a truck move forward if it comes to a quick stop. Explanations should use Newton’s first law. For example, packages in the back of a truck move forward if the truck comes to a quick stop because an object in motion continues its motion ...
