Displacement vectors of 3 m and 5 m in the same direction combine to ma

Physics
1 answer:
andrey2020 [161]3 years ago
6 0

Answer:

The magnitude of the displacement vector will be 8 meters.

Explanation:

Given the vectors:

r= 3 m

s= 5 m

The resulting vector is the sum of the vectors r and s. When we add vectors, the vectors that point in the same direction are added and the vectors that point in opposite directions are subtracted. Therefore, the result will be:

R= r + s = 3 m + 5 m = 8 m

The resulting vector will be 8 m in magnitude and the same direction as the previous vectors.

what will be the moment of inertia of a body if it rotates at a uniform rate of 10rad/sec^2 by a torque of 120Nm?​
Naya [18.7K]

Answer:

12 kgm²

Explanation:

here angular acceleration = 10rad/sec²

torque= 120Nm

moment of inertia=?

we know,

torque= angular acceleration× moment of Inertia

or, moment of inertia = torque/angular acceleration

= 120/10

= 12kgm²

A student pushes on a 20.0 kg box with a force of 50 N at an angle of 30° below the horizontal. The box accelerates at a rate of
PtichkaEL [24]

Answer:

225 N

Explanation:

"Below the horizontal" means he's pushing down at an angle.

Draw a free body diagram of the box.  There are three forces: normal force N pushing up, weight force mg pulling down, and the applied force F at an angle θ.

Sum of forces in the y direction:

∑F = ma

N − mg − F sin θ = 0

N = F sin θ + mg

Plug in values:

N = (50 N) (sin 30°) + (20.0 kg) (10 m/s²)

N = 225 N
