Answer:
F = 104.832 N
Explanation:
given,
upward acceleration of the lift = 1.90 m/s²
mass of box containing new computer = 28 kg.
coefficient of friction = 0.32
magnitude of force = ?
box is moving at constant speed hence acceleration will be zero.
Now force acting due to lift moving upward =
F = μ m ( g + a )
F = 0.32 × 28 × ( 9.8 + 1.9 )
F = 104.832 N
hence, the force applied should be equal to 104.832 N
Answer:
Given a set of vectors, you can determine if they are linearly independent by writing the vectors as the columns of the matrix A, and solving Ax = 0.
Explanation:
1. Volume
2. liquid
3. Gas
4. Kinetic energy?
5.Gas
Initial speed of Gazelle is along x direction and its value will be

also its initial height is given as

Part a)
now from kinematics along Y direction

as we know that





Part b)
distance moved horizontally

as we know that

now we will have

so it will lend at distance of 4 m.
Part c)
final velocity in vertical direction



so net speed will be
