A projectile is launched from the ground with velocity|v|=8 m/s, at an anglefrom the horizontal direction. The projectile would have landed on the ground at the horizontal distanced1away from the launch point, but instead it hit the top of a platform of heighthin the way. The platform was hit at a horizontal distanced2away from the launch point. If it takesttop= 0.54 seconds for the projectile to reach the top of its trajectory, what is the value of the launch angle? Use g = 9.8 m/s²and retain one decimal place for you answer.
