Whit is the final speed of an electron accelerated through a potential difference of 200 V if has an initial speed of 2.0 x 10^6 m/s. (Charge of electron = 1.6 x 10^-19 C and mas of electron = 9.11 x 10^-31 kg)

I worked out part a, I'm stuck with the theoratic part now. Can't really understand the question. Thanks for your replies btw

A hose directs a horizontal jet of water, moving with a velocity of 20ms^-1, on to a vertical wall. The cross-sectional area of the jet is 5 x 10^-4 m^2. If the density of water is 1000kg m^-3: a) fin the rate of change of momentum as the water hits the wall, assuming that the water is brought...

It's my first time writing on this forum, hope I'm posting in the correct section. Problem : A hose directs a horizontal jet of water on to a vertical wall. What is the force on the wall, under the above conditions ? Explain. Thanks for any replies
