A ball leaves a table with an initial horizontal velocity of 2.4 m/s. The height of the table is adjustable. In two runs, the height of the table is set as 2.5 m and 5.0 m respectively. Assume air resistance is negligible. What is the horizontal distance between the two landing locations of the ball?
How many liters of gasoline would give the same mechanical energy given that each liter provides 8.50x10^6 J of mechanical energy.
Two non-conducting infinite planes of uniform surface charge ?1 = 13.11 µC/m2 and ?2 = ?3.5 µC/m2 are parallel to each other and d = 0.129 m apart, What is the electric field outside the planes, at A
