Velocity is speed plus direction, so an example of velocity would be a vehicle traveling at 75mph north. Velocity is a vector quantity because it describes both magnitude and direction.
Answer:
person when the point-light walker is moving
Explanation:
A point light walker is an arrangement of dots that moves in a way that mimics a human walking. This is used in the field of Biological Motion Perception.
Biological motion perception is the science that deals with how our brain perceives motion. In order to understand how the brain perceives motion a point light walker is used.
Choice 'b' is one possible way to state
Newton's second law of motion.
The other choices are meaningless.
The kinds of atoms in the substance and their arrangements
Answer:
Explanation:
Given
time taken
Speed acquired in 2 sec
Here initial velocity is zero
acceleration is the rate of change of velocity in a given time
Distance travel in this time
where
s=displacement
u=initial velocity
a=acceleration
t=time
so Jet Plane travels a distance of 42 m in 2 s
