1) A projectile is launched from the floor with an initialvelocity of 5.0 m/s at an angle of 30 degrees upward ofhorizontal.
a) For how long is the projectile in the air, as measured by theobserver who launches the projectile?
b) How far away horizontally from the launch point does theprojectile land, as measured by the observer who launched it?
c) It turns out that this projectile was launched and landedinside of a vehicle that was traveling at 90% of the speed oflight. It was launched exactly when both observers were at theorigin. To the observer standing on the ground next to (but not in)the vehicle, how long was the projectile in the air?
d) How far from the launch point does the projectile land, asviewed from the observer outside the vehicle?
