Answer:
Velocity, v = 1 m/s
Explanation:
Given that,
Initially Mike walked 450 m due west and then he turned and walked 150 m to the east.
Time taken, t = 300 s
The displacement of Mike is equal to the difference in final position and the initial position.
d = 450 - 150
d = 300 m
Let v is his velocity. It is equal to the net displacement divided by total time taken.
v = 1 m/s
So, the velocity of Mike is 1 m/s. Hence, this is the required solution.
Answer:
The value is
Explanation:
From the question we are told that
The diameter of the storm is
The wind speed is
Generally the radius is mathematically represented as
=>
=>
Generally the angular velocity is mathematically represented as
=>
=>
The initial velocity of the ball is 1.01 m/s
Explanation:
The motion of the ball rolling off the desk is a projectile motion, which consists of two independent motions:
- A uniform horizontal motion with constant horizontal velocity
- A vertical accelerated motion with constant acceleration (, acceleration due to gravity)
We start by analyzing the vertical motion: we can find the time of flight of the ball by using the following suvat equation
where
s = 1.20 m is the vertical displacement (the height of the desk)
u = 0 is the initial vertical velocity
t is the time of flight
Solving for t,
Now we analyze the horizontal motion. We know that the ball covers a horizontal distance of
d = 0.50 m
in a time
t = 0.495 s
Therefore, since the horizontal velocity is constant, we can calculate it as
So, the ball rolls off the table at 1.01 m/s.
