The speed of both cars is the same ... 80 km per hour.
But their velocities are different, because DIRECTION is part of velocity, and their directions are different.
Answer:
Im pretty sure it's C
Explanation:
The answer A talks about constant speed, which does not correspond to Net Force. The answer B, talks about constant velocity, but talks about how much force apposes the box. The answer C talks about the value of the net force acting on the box, so im pretty sure the answer is C.

hope this helps
Answer:
2000years
Explanation:
We will either convert the distance to centimeters or speed to meters/second.
Converting distance to centimeters: 100 meters= 100*100centimeters =10000centimeters.
time=distance/speed
t=10000/5=2000 years
Answer:
1. 
2. 
3. 
4. 
Explanation:
1. The frequency of rotation is given by:
Where:
ω: is the angular speed = 50 rotations (revolutions) in 25 s.
We need to convert the units of ω.
Now, the frequency is:
2. The frequency is:
We know:
5 laps = 5 revolutions
t: time = 450 s
3. The frequency of the pendulum is:
4. We have:
θ: number of revolutions = 48 rev
f = 12 Hz
t =?
The time can be calculated as follows:
