Answer:

Explanation:
From the question we are told that:
initial Speed 
Mass 
Center of mass 
Generally the equation for angular velocity is is mathematically given by


When tectonic plates collide, this is a convergent plate boundary.
When the two plates at a convergent boundary are continental, they form mountains and mountain ranges.
Hope this helps! :)
The formula for momentum is p = mv, where p is momentum, m is mass, and v is velocity.
To solve for p, plug in 750 kg for mass and 30 m/s for velocity. • is a multiplication symbol
p = mv
p = 750kg • 30m/s
p = 22500 kg•m/s
Answer:
Part a)
a = - 8.45 m/s/s
Part b)

Part c)

Explanation:
Part a)
when car apply brakes then the friction force on the car in front of us is given as

here we need to find deceleration due to friction



Part b)
Braking distance of the car is the distance that it move till it stops
so we will have



Part c)
Since we know that average reaction time for human is 0.424 s
now we know that during reaction time our car will travel at uniform speed
so we will have



Answer: E.
Explanation: because the book is on the table, its not really moving in any direction.
