Answer:
The value is
Explanation:
From the question we are told that
The initial speed of the roller coaster is
The length of the hill is
The acceleration of the roller coaster is
Generally the acceleration is mathematically represented as
Here is the initial time which is equal to zero
is the final velocity which is mathematically represented as
So
Solving this using quadratic formula we obtain
Generally time cannot be negative so
Generally the final velocity is mathematically represented as
Answer:
It should fly 8° to west of south at 430km/h
Explanation:
According to the diagram. X components for both velocities must have the same magnitude in order to get the resultant velocity due south.
Solving for α:
α = 8.03°
Answer:
a
The total distance is
b
The displacement is
Explanation:
From the question we are told that
Distance traveled by the ball for first player to the right
Distance traveled by the ball for second player to the left
The total distance traveled by the ball is mathematically represented as
Substituting values
The displacement is mathematically represented as
This is because displacement deal with direction and from the question we are told that right is positive and left is negative
Substituting values
