(b) What analysis model describes the vertical motion of the

protons above the plane? (c) Argue that Equation 4.20

would be applicable to the protons in this situation. (d) Use

Equation 4.20 to write an expression for R in terms of vi

,

E, the charge and mass of the proton, and the angle u. (e)

Find the two possible values of the angle u. (f) Find the time

interval during which the proton is above the plane in Fig-

ure P22.26 for each of the two possible values of u.

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

it's a b and

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)
