Answer: find the answer in the explanation as kinetic energy converts to potential energy.
Explanation:
Before the truck driver sees a dog running into the road, The mechanical energy state of the truck will be kinetic energy at maximum.
Immediately he applied the brakes, the mechanical energy of the truck will be combination of kinetic energy and potential energy.
The kinetic energy will gradually decrease as potential energy continue to increase till it reaches maximum potential energy.
The truck will come to a stop at maximum potential energy
Because animals are animals and humans hopefully don’t want to be treated like animals, also it is preferred that they don’t eat human food like gum or chocolate…
Answer:
speed is 4/3 × g × sin β
acceleration is g sin θ
Explanation:
Given data
mass = M
radius = R
distance = s
angle = β
to find out
final speed and the acceleration
solution
we know that cylinder is rolling on inclined plane
so from conservation of mechanical energy
energy at top = energy at bottom
energy at top will be
= m ×g×h
= m ×g×s sinβ ................1
and
energy at bottom will be
= 1/2 ×m × v² + 1/2 × z × ω²
= 1/2 ×m × v² + 1/2 × 1/2 ×m× r² × (v/r)²
= 3/4 × v² .................2
equating now equation 1 and 2
m ×g×s sinβ = 3/4 × v²
so v = 4/3 × g × sin β
so speed is 4/3 × g × sin β
and acceleration is
= mg sin θ ............3
and
acceleration = ma ............4
now equation equation 3 and 4
ma = mg sin θ
so acceleration is g sin θ
Heat is an energy that is produced from something like the sun. Sound energy is when an object works to make sound. Light is when something gives off light by working. And potential energy is when an object is completely still but can be moved by another force
Vi = 0 m/s
Vf = 27 m/s
t = 9 min = 540 s
1 min = 60 s
9 min = 540 s
a = ? m/s^2.
vf = vi + at
27 = 0 + 540a
27 = 540a
27/540 = 540a/540
27/540 = a
0.05 = a.
The truck's acceleration was 0.05 m/s^2.
