602.496 J I think, I hope this helps!
Answer:
work done by fuel is conversion of chemical energy into mechanical whereas work done by moving object is due to its displacement by the application of force. actually, both of them give same meaning
Answer:
12.35m
Explanation:
Hello! To solve this problem we must consider the following:
1. The car moves with constant speed, which means that the distance traveled is equal to the multiplication of time by speed.
X = VT
we solve the equation for time

2. The bolt moves with constant acceleration, with acceleration of 9.81m / s ^ 2, so we could apply the following equation.
note=remember that "a uniformly accelerated motion", means that if the velocity is plotted with respect to time we will find a line and its slope will be the value of the acceleration, it determines how much it changes the speed with respect to time.

where
Vo = Initial speed
=0
T = time
=1.588s
g =gravity=9.8m/s^2
Y = bridge height
solving

The equation you would use here is F=ma, where F is the force in Newtons, m is the mass in kilograms (must be in kilograms in order for the units to match on both sides), and a is acceleration in meters per second squared. Therefore, you do: 65kg x .3m/s^2= FF. That'll give you the answer.
The acceleration due to gravity only points downward with magnitude g. The angle of the projectile doesn't matter.
