Answer 2

First calculate the time of flight.

Answer 3

v=d/t so im cofused because you don't have time

Answer 4

yes, that is why i am confused too!

so @Abhisar how do we do that?

Answer 5

find the time? with the information given in this problem?

Answer 6

For calculating the time of flight you can use the equation S=ut+1/2at^2

Since the ball was kicked horizontally, the vertical component of velocity will be 0. So you can take u=0, s= height from the level ground.

Answer 7

heyy

Answer 8

@lovinbabe mathway is an excellent website but is not for word problems

Answer 9

okay! so 27=0t+1/2at^2
27=1/2at^2
54=at^2 ? @Abhisar ?

Answer 10

okkkk

Answer 11

Height is 1.8 and not 27, find the value of t.

After that you can use it to find the initial horizontal speed of football.

Answer 12

ohh okay

so we get this?
1.8=1/2at^2
3.6=at^2 ?
? not sure what to do from here?

Answer 13

put the value of a and find t. (a is acceleration due to gravity, take it as 10m/s^2)

Answer 14

okay:)

so 3.6/10=t^2
.36=t^2
t=0.6 ?

Answer 15

@Abhisar ? is that correct? if so, what happens from there?

Answer 16

Yep, now finally use this t too find the horizontal speed.You can again use the same equation but this time s will be 27 m and t = 0.6. find the value of u this time and that will be your answer.

Answer 17

ahh okie!

so 27=u(0.6) + 1/2(10)(0.6)^2
27=0.6u + 1.8
25.2=0.6u
u=42

is that correct? :)

Answer 18

Yes it's correct (if your calculation is correct :P)

Answer 19

Yes...

Answer 20

haha okie thanks so much!! so this is done then? :O

Answer 21

thank you @Abhisar :)
