Answer & Explanation:
A girl is driving a bicycle at a velocity of 30m/s at 40 degree North west.
Considering the above sentence, the magnitude of the bicycle velocity is 30 meters per second and the direction of the motion of the bicycle is 40 degree North west. So, the bicycle is having both magnitude and direction, so the velocity is a vector quantity.
IF the object's motion is graphed, and IF time is plotted
along the x-axis and the object's position is plotted along
the y-axis, then the slope of the graph at every point is the
object's speed at that instant of time.
The white fur reflects all colors, so would appear green.
The black fur reflects no colors, so would still appear black.
Answer:
Yes
Explanation:
Momentum before collision = momentum after collision
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
The cars stick together after the collision, so they have the same final velocity.
m₁u₁ + m₂u₂ = m₁v + m₂v
m₁u₁ + m₂u₂ = (m₁ + m₂)v
Plug in values and solve (take Jay Z's direction to be positive):
(1100) (-20) + (1475) u₂ = (1100 + 1475) (7)
u₂ = 27.1 m/s
Yes, Jay Z was speeding.
