Pretty sure it is B.
Because inertia is a tendency to do nothing or remain unchanged.
Vehicle weight shifts can be backward forward. In this particular case accelerating to fast would cause a shift of weight backwards. Breaking too quickly on the other hand would cause weight to shift forward. You have seen this while in a car or a bus at the traffic light. As the vehicle breaks you are pulled forward as it starts moving you are pulled backwards.
Explanation:
The object stops moving in 5 places (namely B, D, F, H, and position after 28 seconds which isn't marked ).
We know that the object has stopped moving, since its position does not change with the passage of time i.e. at rest.
Answer:
The time taken for the daredevil to travel the 50 m horizontally is 2.83 s.
Explanation:
Given;
angle of projection, θ = 45°
initial speed of the projectile, u = 25 m/s
horizontal distance traveled by the projectile, x = 50 m
The time taken for the daredevil to travel the 50 m horizontally is calculated as;
where;
is the horizontal component of the velocity = uCosθ
Therefore, the time taken for the daredevil to travel the 50 m horizontally is 2.83 s.
Answer:
C
Explanation:
The answer is c because Newton’s third law states “ for every action there is an equal and opposite reaction.” Since the car quit moving the book did not stay at rest because there was a reaction.
