A 10 kg projectile was launched at the horizontal ground at a velocity of 20 m/s, 10 degrees with respect to the horizontal. The projectile hit a 30 kg box on top of a table at 0.177 seconds. If the box developed a speed of 5.140 m/s after impact, what is the speed of the projectile after the collision? Please include FBD.
Comic-strip hero Superman meets an asteroid in outer space and hurls it at 800 m/s, as fast as a bullet. The asteroid is a thousand times more massive than Superman. In the strip, Superman is seen at rest after the throw. Taking physics into account, what would be his recoil velocity?
A 1500 kg weather rocket accelerates upward at 10.0 m/s2. It explodes 2.00 s after liftoff and breaks into two fragments, one twice as massive as the other. Photos reveal that the lighter fragment traveled straight up and reached a maximum height of 530 m. What were the speed and direction of the heavier fragment just after the explosion?
