Q. Two objects are thrown simultaneously from the same height but at different angles. If one is thrown at 30 degrees and the other at 60 degrees, which will land first?
A.
30 degrees
B.
60 degrees
C.
Both land at the same time
D.
Depends on the initial speed
Solution
Both will land at the same time as they are thrown from the same height.
Q. Two objects are thrown simultaneously from the same height but at different angles. If one is thrown at 30 degrees and the other at 60 degrees, which will hit the ground first?
A.
30 degrees
B.
60 degrees
C.
Both hit at the same time
D.
Depends on the speed
Solution
Both will hit the ground at the same time as they are thrown from the same height.
Q. Two objects are thrown simultaneously from the same height but at different angles. If both have the same initial speed, which will hit the ground first?
A.
Object at 30 degrees
B.
Object at 45 degrees
C.
Object at 60 degrees
D.
Both hit at the same time
Solution
All objects hit the ground at the same time if launched from the same height with the same speed.
Q. Two objects are thrown simultaneously from the same height but at different angles. If one is thrown at 30 degrees and the other at 60 degrees, which one will have a longer range?
A.
30 degrees
B.
60 degrees
C.
Both have the same range
D.
Cannot be determined
Solution
The range is maximum at 45 degrees; hence, the 30-degree projectile will have a longer range than the 60-degree one.
Q. Two objects are thrown simultaneously from the same height but at different angles. If one is thrown at 30 degrees and the other at 60 degrees, which will have a greater range?
A.
30 degrees
B.
60 degrees
C.
Both have the same range
D.
Cannot be determined
Solution
Both angles will have the same range when launched from the same height.
