    Final speed of an accelerated electron

    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)

    What is the Force on a Wall from a Horizontal Water Jet?

    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...
