A 1,300 kg car moving at 20 m/s and a 900 kg car moving at 15 m/a in precisely opposite directions crash head on. If we consider this event to be a perfectly inelastic collision, what is the speed of the cars after the impact?
Answers
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

Second is <8 : 65
Answer:
(x, y) → (x - 2, y + 8)m∠8 = 65°Step-by-step explanation:
Q1The translation is the difference between two corresponding points:
-2 - 0 = 26 - (-2) = 8Correct option is C
(x, y) → (x - 2, y + 8)Q2∠8 and 115° are supplementary and sum to 180°
m∠8 = 180° - 115° = 65°The storage box for a flag is in the shape of a triangular prism. What is the surface area of the box?
Answers
*see attachment for the diagram of the triangular prism box
Answer:
528.8 in.²
Step-by-step explanation:
Surface area of triangular prism = 2(BA) + P*H
Area of triangular base (BA) = ½*b*h
b = 24.5 in.
h = 12 in.
BA = ½*24.5*12 = 147 in.²
Perimeter of triangular base = 24.5 + 17.1 + 17.1 = 58.7 in.
Height of prism = 4 in.
Plug in the values into the surface area formula:
Surface area of prism = 2(147) + 58.7*4
= 294 + 234.8
= 528.8 in.²
