Answer:
d = 186.3 m
Explanation:
Given that,
Speed of Matthew 3.45 m/s due eastward
It takes 54 seconds to walk to the store.
We need to find the distance covered. The product of speed and time is equal to the distance covered.
d = vt
Putting all values,
d = 3.45 m/s × 54 s
d = 186.3 m
Hence, he will cover a distance of 186.3 m.

Answer:
Velocity in the first part= 0.75 m/s
Velocity in the second part= 1.1 m/s
Velocity in the third part= 0.92 m/s
Explanation:
Conceptual analysis : The velocity is defined by the following formula:
v= d/t
Where:
v : velocity in The speed in meters over second (m/s)
d : distance in meters (m)
t : time in seconds (s)
Problem development
velocity in the first part= 0.75 m/s
velocity in the second part= 1.1 m/s
velocity in the third part= 0.92 m/s
When you give your body a drug it automatically starts to build a tolerance and immunity.
Answer:
Her speed at the bottom of the slope is 25.665 m/s
Explanation:
Here we have
Initial velocity, v₁= 15 m/s
Final velocity = v₂
The energy balance present in the system can be represented as
Where:
m = Mass of the cyclist = 70 kg
W = work done by the drag force = 
Where:
d = Distance traveled = 450 m
Therefore,
and
= 658.714 m²/s²
v₂ = 25.665 m/s
Her speed at the bottom of the slope = 25.665 m/s.
