Answer:
17.96m/s
Step-by-step explanation:
Based on law of conservation of momentum;
m1u1 +m2u2 =(m1+m2)v
v is the velocities of the car after impact
Substitute the given values
1300(20)+900(15) = (1300+900)v
26000 + 13500 = 2200v
39500 = 2200v
v = 39500/2200
v = 17.96m/s
Hence the speed of the cars after impact is 17.96m/s
There are three outcomes of 4 out of eighteen outcomes, so the fraction of angle of spinner numbered 4 is
Answer:
0.52
Step-by-step explanation:
The hundredths position is the second spot to the right of the decimal point, so 52/100 can be written as 0.52.
Hello!
You can classify a triangle by its sides or by its angles
Since all the sides are different it is a scalene triangle.
Since one angle is 90° it is also a right triangle.
Those are the two different ways
Hope this helps.
