Answer:
The 43kg student will be sliding at 1.79m/s opposite the direction the 34kg student is going.
Explanation:
Conservation of linear momentum!
The law of conservation of momentum says that in an isolated system, the momentum before must equal the momentum after:
.
For our two students
(notice the - sign in -2.4m/s, this means going to the left)
since the students were not moving at first, , therefore we have
solving for gives
Hence the 43kg student will be sliding at 1.79m/s to the right.
answer:
The horizontal component of the 600 N force is,
Fx = 600 cos(30) 519.61 N
The vertical component of the 600 N force is,
Fy = 600 sin(30) = 300 N
hope it's help!
Answer: 20.73 m/s
Explanation:
The centripetal force is given by the following equation:
(1)
Where:
is the centripetal force
is the mass of the car
is the centripetal acceleration
Isolating :
(2)
(3)
(4)
Now, there is a relation between the centripetal acceleration and the tangential velocity:
(5)
Where is the tangential velocity and is the radius of the circular path, which can be found if we know its length :
(6)
(7)
(8)
(9)
Substituting (4) and (8) in (5)
(5)
Finding :
Answer: <u><em>2.03259656 × 10^8</em></u>
Explanation:
1.5 x 10 = 15
√(15) = <em>3.87</em>
<u><em>put this to the side until we sum everything up..</em></u>
3.5 × 10 = 35
35 ^ 5 = <em>52521875</em>
So, now lets sum it all up....
(3.87) x (52521875) = <u><em>203259656.25</em></u>
but in scientific notation it is: <u><em>2.03259656 × 10^8</em></u>
