Answer:
a) Y component of the vector =15.54 m
b) Vector magnitude = 21.6 m
Explanation:
The given vector makes 44 degree angle with Y axis, as given. This is same as 90 -44 = 46 degrees with the horizontal or X axis.
b) X component of the given vector = = A cos 46 =15
⇒ A = 15/cos 16 = 21.6 m = Total vector magnitude.
a) Y component of the vector = 21.6 sin 46 = 15.54 m
b) A = 21.6 m

Answer:
43,232 trillion km
Explanation:
Light year is the unit of distance. It is very big unit and used to measure the distances between the heavenly bodies.
1 light year = 9.46 trillion Km
So, convert 4570 light year into Km
= 4570 x 9.46 = 43232.2 trillion Km
So, the answer is 43,232 trillion Km
Answer:
Explanation:
given,
mass of the cart 1, m₁ = 310 g
speed of car 1 , v₁ = 1.25 m/s
mass of cart 2, m₂ = 260 g
speed of cart 2, v₂ = -1.33 m/s
speed of center of mass
Hence, speed of center of mass of the system is equal to 0.0732 m/s
