1. The horizontal distance covered by a projectile in
trajectory motion is maximized at which angle? _____
2. A ball is thrown at 20 m/s at 30 degrees. The
horizontal velocity component at the end of the flight is
3. In trajectory motion, the initial horizontal
velocity is _____ the final horizontal velocity.
4. In trajectory motion, the vertical acceleration is
_______.
5. A projectile is launched at an angle of 60 degrees
at 50 m/s. How far has it traveled after 12 seconds?
6. The time it takes to get to the highest point of the
path is ________ the total hang time of an object in trajectory motion.
7. A rock is thrown at 9475 m/s at 26.897 degrees and
hits the ground 20 seconds later. If we consider air (moving at a
constant velocity with constant density) as a factor in its flight, how
long did it take to reach the highest point in its flight?
8. A rocket is launch at a speed of 400 m/s at an angle
of 90 degrees. How high does it go?
9. A football is thrown at 85 m/s at an angle of 45 degrees.
How far does it go before hitting the ground?
10. Kevin throws a softball to John at 40 m/s at an angle
of 70 degrees. How high does it get and how long does it take to
get to that maximum height? How far away is John and how long does
it take for the softball to get to him?
11. A bazooka is fired at 1200 m/s at an angle of 70
degrees. How high does it get and how long does it take to get to
the maximum height? How far (along the ground) does the shell travel
and how long does it stay in the air? |
