5/36 MCQs for:
Kinematics in Two Dimensions: Vectors, projectiles
If the acceleration of an object is always directed perpendicular to its velocity:
The object is turning.
The object is speeding up.
This situation would not be physically possible.
The object is slowing down.
A swimmer heading directly across a river 200 m wide reaches the opposite bank in 6 min 40 s. She is swept downstream 480 m. How fast can she swim in still water?
1.2 m/s.
1.4 m/s.
1.8 m/s.
0.50 m/s.
A plane flying horizontally at a speed of 50.0 m/s and at an elevation of 160 m drops a package. Two seconds later it drops a second package. How far apart will the two packages land on the ground?
162 m.
100 m.
177 m.
283 m.
You are trying to cross a river that flows due south with a strong current. You start out in your motorboat on the east bank desiring to reach the west bank directly west from your starting point. You should head your motorboat
Due north.
In a southwesterly direction.
In a northwesterly direction.
Due west.
Ignoring air resistance, the horizontal component of a projectile's velocity:
Is zero.
Continuously decreases.
Continuously increases.
Remains constant.
