Question
1. You and your siblings are given a bunch of plastic dart guns as gifts. Before the family warfare begin, you decide to calculate then maximum horizontal range of your dart gun to assist you in determining your strategy. You shoot one dart straight up in the air and time that it takes 5.0 s for the dart to land back on the gun. What is the maximum range of your dart gun?
2. You are playing Indiana Jones with your cousin and find that if you get a running start, jump and leave the ground at a 45
Explanation / Answer
it takes 5 seconds to go up and come down
v = u - gt
v = 0 at the highest point
u = 9.8 x 2.5 = 24.5 m/s
range = u^2 sin 2theta / g
max range = u^2/g = 24.5 x 24.5 / 9.8 = 61.25m
please dont post multiple questons in a single question
In that case only the 1st question will be answered
