Answer:
Explanation:
Height of the cliff is given as
now the time taken by the diver to hit the surface is given as
Now in the same time it has to cover a distance of 13.39 m
so the speed in horizontal direction is given as
Answer:
(A) 7.9 m/s^{2}
(B) 19 m/s
(C) 91 m
Explanation:
initial velocity (U) = 0 mph = 0 m/s
final velocity (V) = 85 mph = 85 x 0.447 = 38 m/s
initial time (ti) = 0 s
final time (t) = 4.8 s
(A) acceleration =
= = 7.9 m/s^{2}
(B) average velocity =
= = 19 m/s
(C) distance travelled (S) = ut +
= (0 x 4.8) + = 91 m
