Answer:
A force that resists motion between two objects that are in contact; rubbing together of two objects = <em>Friction</em>
<em />
The tendency of an object to float = <em>Buoyancy</em>
<em />
A push or pull; any quantity that produces or is capable of producing motion = <em>Force</em>
<em />
A universal force that every mass exerts on every other mass; this keeps us down on earth = <em>Gravity</em>
<em />
A free body diagram is a diagram that labels all the forces acting on an object. This allows us to find the net force on an object = <em>Free body diagram</em> (it literally says it in the definition lol)

My answer -
You can tell the speed of a car at any instant by looking at curved path but it does not move with the average speed of any object moving in a straight line.
P.s
Happy to help you have a AWESOME!!!! day ^-^
Answer:
0.82052 m
Explanation:
potential energy of spring = kinetic energy
=> 0.5kx^2 = 0.5mv^2
=> 

v= 3.11127 m/s
angle = 37°
thus height = distance×sin(37) = D×0.60182
Also,
m×g×h = 0.5×m×v^2
=> 2×9.8×D×0.60182 = 0.5×2×3.11127×3.11127
=> D = 0.82052 m
