Review conceptual example 5 and concept simulation 3.1 before beginning this problem. you are traveling in a convertible with the top down. the car is moving at a constant velocity of 18.6 m/s, due east along flat ground. you throw a tomato straight upward at a speed of 12.8 m/s. how far has the car moved when you get a chance to catch the tomato

d=48.55m

Explanation:

We will calculate for how long the tomato was in the air, and then how much the car moved in that time.

Since the tomato is in accelerated motion (free fall) we can write .

We want t from here:

We want the time the tomato was in the air. Taking the upward direction as positive, and taking into account that its final velocity will be the same as the initial velocity but directed downwards, we have:

(We could have done this by calculating the time to reach maximum height, where the final velocity is 0m/s, and multiply the result by 2 since the time for going up is the same as the time for going down).

The car moves at constant speed, so its displacement will be , and substituting the values we have we get:

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
