Answer:
5 m/s
Step-by-step explanation:
According to law of conservation of momentum :
m1u1 + m2u2 = m1v1 + m2v1
m1 = 7kg ; u1 = 9m/s ; m2 = 2kg ; u2 = 0 ; v2 = 14 m/s
m = masses ; u = initial velocities ; v = final velocities
m1u1 + m2u2 = m1v1 + m2v1
7*9 + 2*0 = 7*v + 2*14
63 + 0 = 7v1 + 28
63 = 7v1 + 28
63 - 28 = 7v1
35 = 7v1
v1 = 35 / 7
v1 = 5 m/s

A plane travels south for 120 km. The plane then travels north for 45 km.
If north is taken as the positive direction, what is the displacement of the plane?
a. 75 km
b. –75 km
c. 165 km
d. –165 km
Answer:
b. -75
Step-by-step explanation:
It is already stated in the problem that north direction is positive. Hence, south is negative.We take 120km south to be -120km.Then, travelling north by 45km.We then add the two: -120km + 45km = -75km3 + x, when the value of x is 15

1. √3 csc x + 2 = 0
Step-by-step explanation:
√3cscx + 2 = 0
cscx = -2/√3
sinx = 1/cscx = -√3/2
We have the basic angle x = 60°.
(Because sin60° = √3/2)
Since sinx is negative, it must fall in Quadrants III or IV.
=> x = 180° + 60° or x = 360° - 60°
=> x = 240° or x = 300°.

D. 75% of the stickers are stars.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Katarina bought a package of 500 stickers. 25% of the stickers are hearts. The remaining stickers are stars.
Now,
Since, Katarina bought a package of 500 stickers. 25% of the stickers are hearts. The remaining stickers are stars.
Hence, The number of hearts = 25% of 500
= 25/100 × 500
= 25 × 5
= 125
And, Number of stars = 500 - 125
= 375
= 75% of 500
Thus, The correct statement are;
B. Katarina has 375 star stickers.
D. 75% of the stickers are stars.

Given that DE is a midsegment for ABC and the length of DE is 8 units. What is the length of BC?
Answer:
BC = 16 units
Step-by-step explanation:
Since DE is the midsegment of the triangle, based on the midsegment theorem, thus:
DE = ½(BC)
DE = 8 units
Plug in the value
8 = ½(BC)
Multiply both sides by 2
2*8 = BC
BC = 16 units
