Question

A ball is projected horizontally from the top of a hill with a velocity of 30m/s.If it reaches the ground 5 seconds later, calculate the height of the hill, take g=10 metres per second square.

Answer 1

same answer

Answer 2

U=30m/s
T=5secs
H=?
S=ut+1/2gt^2=0×5×4^2=80metres

Answer 3

H=ut +1/2gt×t
30×5+1/2×10×5×5
150+125
=275

Answer 4

a Ball is projected horizontally from the hill with a velocity of 30m if it reaches the ground 5seconds later calculate the height

Answer 5

My answers is 125 why

Answer 6

H=ut+1\2gt"2 but since its horizntally from the top of a hill,the laws says that u=0,so it will be 1\2gt"2,1\2*10*5"2=5*25,then the answer is 125m
