A hand grenade is thrown at an angle of 35 degrees from the horizontal at a speed of 58 miles/hour. 1.6 seconds after it is launched, it blows up.
1. How high above the ground is it? (ft)
2. How far is it from the thrower?
My answers come out to:
1. 39 ft
2. 111.5 ft
I'm fairly certain about the second one, but I'm not sure about the first answer. Help?
Thanks.

Hi its been awhile since I did physics but I hauled out the text and my answers were awful close to yours to the same significant figures anyway.
Good job, and thanks for asking for a check on your own work instead of just demanding an answer like many do!!!!!!
cheers

For answer 1, I just approximated (I took a shortcut) a got just short of 39 ft.
For answer 2, I solved it and got 111.5 ft.

if the guy didnt cover himself after he threw it, i don't think he would care about how high or far it went lol
