1. The problem statement, all variables and given/known data A 20.0–kg particle is shot horizontally with an initial speed v0 = 10 m/s at a height of 100 m above the ground level (see figure). The particle explodes into identical fragments when its velocity makes an angle of 35° below the horizontal. Immediately after the explosion, one fragment moves down vertically; while the other fragment moves initially horizontally. (Neglect the effect of gravitational force during the explosion). a) How much energy is released in the explosion? b) At what times will the two fragments reach the ground? 2. Relevant equations 3. The attempt at a solution I didn't reach to the answers yet ,, i just got Vy at angle (35) and it's Vy=7 m/s and i dont know what else to do ,, any ideas ??
