Suppose the stone is thrown at an angle of 39.0° below the horizontal from the same building as in the Example above. If it strikes the ground 47.8 m away, find the following. (Hint: For part (a), use the equation for the x-displacement to eliminate v0t from the equation for the y-displacement.)(a) the time of flight sThe x coordinate as a function of time is x(t) = vcos(39.0)t, so the initial speed is v0 = Δx/(cos 39.0Δt), where Δx = 47.8 and Δt is the time of flight. Insert this into your equation for y(t) and solve for the time of flight. Note that the answer should be smaller than 3.16227766016838, since the stone is thrown down (and to the right).(b) the initial speed m/s(c) the speed and angle of the velocity vector with respect to the horizontal at impactspeed m/sangle °
Answer:
mechanical energy
Explanation:
Mechanical energy is the combination of both potential energy and kinetic
Mechanical energy can be divided as
1)kinetic energy, this energy vis regarded as the energy of motion
2) potential energy which is the stored energy of position.
Mechanical energy reffered to as
motion energy this energy is responsible for the movement of an object based on its position as well as motion.
Mechanical energy= U + K
Where U= potential energy
K= Kinectic energy
As the tire is sitting on top of a ramp, it posses "potential energy" as it is released and rolls down the ramp the potential is converted to Kinectic energy
Answer:
Carbon dioxide and water
Explanation:
The products of complete combustion are always carbon dioxide and water.
The balanced reaction is:
4 CH₃OH + 3 O₂ → 4 CO₂ + 2 H₂O
The energy from the sun that reaches the corn is about two billionths.
