The electric potential V in the space between two flat parallel plates 1 and 2 is given (in volts) by V = 2200x2, where x (in me
ters) is the perpendicular distance from plate 1. At x = 1.7 cm, (a) what is the magnitude of the electric field and (b) is the field directed toward or away from plate 1?
A projectile is launched from and returns to ground level, as the figure shows. There is no air resistance. The horizontal range of the projectile is measured to be R= 167 m, and the horizontal component of the launch velocity is v0x = 22.0 m/s. Find the vertical component v0y of the projectile
The answer to thi question is actually quite simple. Since the car goes for 3.4 seconds, and it goes 75 metres every second, the answer is just 3.4 multiplied by 75 Metres.
