Answer
given,
force = 94 lb
weight of crate = 220 lb
Assuming the static friction be equal = 0.47
kinetic friction = 0.36
Maximum force applied to move the object is when object is just start to move.
F = μ N
F = 0.47 x 220
F = 103.4 lb
As the frictional force is more than applied then the object will not move.
so, the friction force will be equal to the force applied on the object that is equal to 94 lb.
hence, the direction of force will left.
The energy chain diagram in this case is chemical energy >> energy conversion >> motion (kinetic) energy + thermal energy.
<h3>What is an energy chain diagram?</h3>
An energy chain diagram is a graphic representation indicating the conversion between different types of energies.
Kinetic energy is a type of motion (movement) energy generated by using potential (stored) energy.
Chemical energy (in this case, the fuel of the car) is a type of energy that is stored to perform work.

Constant speed along the inclined surface = 30 m / 4 s = 7.5 m/s
Vertical speed = inclined speed * sin(45) = 7.5 *√2 / 2 = 5.3 m/s
Answer: 5.3 m/s
LiCl, because lithium (Li) has one positively charged ion (1+), and
chloride (Cl) has one negatively charged ion (1-), so they
cancel each other out.
