Asked Oct 10, 2019

One strategy in a snowball fight is to throw a snowball at a high angle over level ground. While your opponent is watching this first snowball, you throw a second snowball at a low angle and time it to arrive at the same time as the first. Assume both snowballs are thrown with the same initial speed 20.5 m/s. The first snowball is thrown at an angle of 68◦ above the horizontal. At what angle should you throw the second snowball to make it hit the same point as the first? The acceleration of gravity is 9.8 m/s 2 . Answer in units of ◦ .

Step 1

Given:

For first ball, θ_{1} = 68^{ο}

initial velocity for both the balls, u = 20.5 m/s

for second ball, θ_{2} = ?

Step 2

since distance covered by both the balls is same.

Therefore,...
