Answer:
The magnitude of the hiker’s displacement is 2.96 km
Explanation:
Let the initial displacement of the hiker, = x = 2km
the final displacement of the hiker, = y = 1.4 km
The resultant of the two vectors, According to Pythagorean theorem is the vector sum of the two vectors.
R' = x' + y'

Just do energy spent divided by time to get your answer :). With this we can say a human might be able to!
Answer:
1. 310 N
2. 310 N
Explanation:
1. Determination of the net force.
Force applied (Fₐ) = 430 N
Force experience (Fₑ) = 120 N
Net force (Fₙ) =?
Fₙ = Fₐ – Fₑ
Fₙ = 430 – 120
Fₙ = 310 N
Hence, the net force acting on the crate is 310 N
2. Determination of the net force.
Force applied (Fₐ) = 375 N
Force of friction (Fբ) = 65 N
Net force (Fₙ) =?
Fₙ = Fₐ – Fբ
Fₙ = 375 – 65
Fₙ = 310 N
Hence, the net force acting on the crate is 310 N.

Answer:kinetic energy is less than Potential Energy at bottom
Explanation:
Given
Brick is drop from top of tower
suppose brick Potential Energy at top is U=C
Kinetic Energy(K) of brick is =0 at top of building
Just before hitting its Potential Energy is converted to kinetic energy and some is lost due to the friction.
Therefore kinetic Energy is less than the potential energy
at bottom K < U
