Force = 202,200 x 1.5 ms.q
Force = 303,000 newtons
Answer:
They don't have equal velocities
Explanation:
We have one bus travelling from Chicago to New York at 30 m/s and one bus travelling from Chicago to San Francisco at 30 m/s.
This is a cheat question. You need to remember that velocity is a vector. Remember that a vector has a direction and a module. So, the answer will be true, if both buses meet both conditions (direction and module). Let's start to analyze:
Module: In this case is 30 m/s for both buses
Direction: In this case is where the buses are heading. One is going to New York, and one is going to San Francisco. So the directions are different.
As module and direction are not the same for both buses we can say that they don't have equal velocities.
Answer:
O B. when the angle between the force and displacement is 90°
Explanation:
<h3>work defined as
. </h3><h3>work can only be done if object moves(displacement) in the direction of force. now a quick one. if you since the varrious angles into the cosine, you would see that Cos 90 will give zero which implies that no work is done. Again, angle means it is perpendicular and so it is not in the direction of force.</h3>
