Answer:
there will be collision
Explanation:
= speed of sue = 34 m/s
= speed of van = 5.20 m/s
= speed of sue relative to van = = 34 - 5.20 = 28.8 m/s
= stopping distance after brakes are applied
= distance between sue and van = 160 m
= final speed of sue = 0 m/s
= acceleration = - 1.80 m/s²
Using the kinematics equation
m
Since
hence there will be collision
Answer:
so you know the units in the problem and answer are the same, if they aren't you have to convert them to the same units.
An object in motion tens to stay in motion so if one is not wearing their seatbelt they will be thrown across a car or even out of the car. The car is in motion and so is the perso in it so when it hits somthing the car stopes but the person does not because they are not wearing their seatbelt.
Answer:The 50-kg has the greater potential energy because it has greater mass
Explanation:
Simplicity of conducting the study is to archival research; as ability to test large numbers participants is to survey.
