2. A stone is thrown upwards with an initial velocity of 25 m/s at
an angle of 30° to the ground.
a) Show that the vertical component of the velocity at the start
is 12.5 m/s upwards.
b) Without doing any calculations, state what the stone's
vertical velocity will be when it again reaches ground level.
c) Using the answer to a), show that the stone will rise to a
height of about 8 m.
d) How long will it take for the stone to reach its maximum
height?
e) How long will it take between when the stone was thrown
and when it comes back to the ground?
f) Explain why the horizontal component of the stone's
velocity at the start is 21.7 m/s.
g) What will the stone's horizontal velocity be just before it lands?
h) Use the answers to parts e)-g) to work out the stone's
horizontal range.

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
