Its not a A or B cause the core is the hottest. Its not D either the answer is D
Answer:
3.33m/s
Explanation:
Speed is the change in distance of a body with respect to time.
Speed = Distance/Time
Given
Distance = 1100m
Time = 330s
Speed = 1100/330
Speed = 3.33m/s
Hence her average speed in m/s is 3.33m/s
Answer:
Explanation:
Force = mass * acceleration.
The final speed of the SUV given the data from the question is 9.79 m/s
<h3>Data obtained from the question</h3>
- Mass of car (m₁) = 1200 Kg
- Velocity of car (v₁) = 5 m/s
- Mass of SUV (m₂) = 2600 Kg
- Velocity of SUV (v₂) = 12 m/s
- Final velocity (v) =?
<h3>How to determine the final velocity of SUV</h3>
From conservative of linear momentum,
momentum before impart = momentum after impart
m₁v₁ + m₂v₂ = v(m₁ + m₂)
Thus, we shall determine the final velocity of the SUV by obtaining the velocity after impart. This can be obtained as follow:
v = (m₁v₁ + m₂v₂) / (m₁ + m₂)
v = [(1200 × 5) + (2600 × 12)] / (1200 + 2600)
v = [(6000 + 31200)] / 3800
v = 37200 / 3800
v = 9.79 m/s
Thus, the final velocity of the SUV is 9.79 m/s
