Answer 1

1 over 91^1/12 - I used a surds calculator online! Hope this helps. Please mark as brainliest if this answer is correct

Answer 2

Answer:-2.61 m/s
Explanation:
This problem can be solved by the Conservation
of Momentum principle, which establishes that
the initial momentum Po
must be equal to the final momentum PI
Po = P$ (1)
Where:
Po=mV. + NUE
(2)
PI = (m + M)V,
(3)
M = 1200kg
is the mass of the first car
V. = 20m/s
is the velocity of the first car, to the North
M = 1400kg
is the mass of the second car
Ua
=-22m/s
is the mass of the second car, to the South
is the final velocity of both cars after the collision

(4)
Isolating
5)
(6)
Finally:
VI=-2.61m/s
(7) This is the resulting velocity of the
wreckage, to the south
