During volcanic eruption chunks of slid rock are blasted out of the volcano . (a) At what initial speed

Wou ld a valcanic object have to be ejected at `37^(@)` to the horizontal from the vent A in order to fall at B as shown in Fig. 5.22? (b) what is the time of flight? (g=9.8`m//s^(2)`)

If the body travels half its total path in the last second of its fall from rest, find: (a) The time and (b) height of its fall. (g=9.8 m//s^(2))

A particle is projected horizontally with a speed V=5m/s from the top of a plane inclined at an angle theta=37^(@) to the horizontal (g=10m//s^(2)) What is the velocity of the particle just before it hits the plane?

A ball of mass 200 g falls from a height 5 metres. What is its kinetic energy when it just reaches the ground ? ( g = 9.8 m//s^(2) ).

From what height should a stone be dropped so that the ratio of the distances traveled during the first and the last second of the fall is 1:9 ? Find the total time of its fall. [ g = 9.8 "m.s"^(-2) ].

From the top of a cliff 73.5 m a body is projected with a velocity of 19.6 m/s at an angle of 30^@ with the horizontal. Determine the time of flight, the distance from the foot of the tower and velocity with which the body strike the ground. g =9.8 m/ s^2

An electron and a proton are allowed to fall through the separation the plates of a parallel plate capacitor of voltage 5 V and separation distance h = 1 mm as shown in the figure . (a) Calculate the time of flight for both electron and proton (b) Suppose if a neutron is allowed to fall what is the time of flight ? (c ) Among the three which one will reach the bottom first? ( Take m_(p) = 1.6xx10^(-27)kg , m_(c) = 9.1 xx10^(-31) " kg and g " = 10 ms^(-2))
