In a tv set, an electron beam moves with horizontal velocity of 4.8 x 10^7 m/s across the cathode ray tube and strikes the screen, 50cm away. how far does the electron beam fall while traversing this distance?

Explanation:

hence making time the subject then

Substituting 50 cm which is equivalent to 0.5 m for distance and velocity as given as we obtain

From kinematic equation

and taking g as 9.81 then

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.

i think its d if wrong im sorry
