Q1. An electron with initial velocity v0 = 1.15 × 10^5 m/s enters a region 1.0 cm long where it is electrically accelerated. It emerges with velocity v = 5.51 × 10^5 m/s. What is its acceleration, assumed constant?

Q2. A proton orbits a long charged wire, making 2.00 times 10^ {6} revolutions per second. The radius of the orbit is 1.40 cm.
What is the wire's linear charge density?

Q3. A 71.0 g bullet travelling at 280 m/s penetrates a block of ice at 0 C and comes to rest within the ice.
