An astronaut is on a spaceship where the acceleration is constant and given by the formula:
a=(3m)i+(5m)j
Here, i and j are the unit vectors along the x- and y-axes, respectively.
The astronaut throws a dart so it starts from the origin and travels in the xy plane under the
influence of the above acceleration. The dart's initial velocity is (6 m) j
The dart's initial x-coordinate is [Select]
m and its initial y-coordinate is
[Select]
m
The x-component of the dart's initial velocity is [Select]
m/s and the y-
component of the dart's initial velocity is [Select]
m/s.
The x-component of the acceleration is [Select]
m/s2 and the y-component
of the acceleration is[ Select ]
m/s2
Answer the following for the instant when the dart's x-coordinate is 18 m
- the elapsed time since the beginning of the dart's flight is about[Select]
- the dart's y-coordinate is about [Select]
- the x-component of the dart's velocity is about [Select]
m/s
- the y-component of the dart's velocity is about [Select ]
m/s
- the dart's speed is about [Select]
m/s
- the magnitude of the dart's acceleration is about [Select]
m/s2.
