Question

(01
a) A bullet thrown vertically upwards with a speed of 19.6 ms-l
form the top of a tower returns to the earth in 6 s. Find the
height of the tower.
b) A man can through a ball to a maximum horizontal distance of
100 m. To what maximum height can he thrown the same ball?​

Answer 1

Answer:

294m,50m

Explanation:

a) Considering -y direction as positive,

s = ut +1/2at^2

h = (-19.6)x6 + 1/2x 9.8x 6^2

h= 294m

b) Maximum range = u^2 /g = 100m

maximum height = u^2 /2g = 100/2= 50m
