Answer:
47 kg
Explanation:
Momentum = 2209 kg * m/s
velocity = 47 m/s
Mass (m) = ?
We know that momentum is the product of mass and velocity so
Momentum = mass * velocity
2209 = mass * 47
mass = 2209 / 47
mass = 47 kg
Hope it will help :)❤
I’m pretty sure it’s a starting point... unless it’s asking for an actual object

To find the distance b you want to find the vector that goes from A to 15 km E (vector C). Calling the differnce in A + B and C D, then we know
[math]D = (A + B) - C. So we have for D:
Dx=(Ax+Bx)â’Cx=â’1.8178Dx=(Ax+Bx)â’Cx=â’1.8178
Dy+(Ay+By)â’Cy=1.7883Dy+(Ay+By)â’Cy=1.7883

Answer:
Fr = 26.83 [N]
Explanation:
To solve this problem we must use the Pythagorean theorem, since the forces are vector quantities, that is, they have magnitude and density. Therefore the Pythagorean theorem is suitable for the solution of this problem.
