A. What is force because yeah are using force to pull back on the bow
Answer:
Deceleration = 5.7 m/s²
Explanation:
We are given;
Deceleration of the car; d = -3.15 m/s²
Angle of inclination; θ = 9.7°
Coefficient of friction will be calculated as; μ = d/g = 3.15/9.81 = 0.3211
Now,the acceleration would be gotten from the formula;
a = g (sin(θ) + μ cos(θ))
Plugging in the relevant values to give;
a = 9.81[sin 9.7 + (0.3211 × cos (9.7)]
sin 9.7 and cos 9.7 are in radians, thus we have;
a = 9.81(-0.2718 + (0.3211 × -0.9624))
a = -5.7 m/s²
Negative acceleration means a Deceleration of 5.7 m/s²
All fossil fuels are formed deep underground. they are all nonrenewable energy

Answer:
<u>Work done by the force acting on a body is defined as the product of force and displacement of the body in the direction of the force.</u><u> </u> It is a scalar quantity. Force acting on the body must produce a displacement for the work is to be done by the force. Thus, for the work to be done, the following conditions must be fulfilled:
A force must be applied and the applied force must produce a displacement in any direction except perpendicular to the direction of the force.
Mathematically,
( in the direction of force)
i.e W= F•D
The SI unit of force is Newton (N) and that of displacement of a metre (M). So the unit of work is Newton metre(Nm) which is joule (J).
Thus, one joule work is said to be done when one Newton force displaces a body through one metre in its own direction.
Hope this helps...
Good luck on your assignment..
