Answer: Image for option 4
Explanation:
The fourth option is correct because there are three forces acting on the block:
which is the <u>Friction force</u> and acts against the movement of the block
the <u>Normal Force</u>, which is perpendicular (normal) to the surface of the rough ramp
the Weight of the block, which is the force due gravity acceleration and has an <em>x-component</em> and an <em>y-component.</em>
Answer:
1287.5 N
Explanation:
We are given that
Mass of vehicle ,m=2100 kg
Weight of vehicle ,F=20,600 N
Area,A=
We have to find the minimum force that must be applied to the attached piston of area in order to lift the vehicle.
Apply the pascal's law
Using the graph, which describes how Henry ran the 100m race;
a) It takes Henry 20seconds to run 100m
b) Henry's average speed over the race is; 5m/s.
According to the linear graph which describes the distance ran by Henry during the 100m race as a function of time.
a) Since the distance from start ran by Henry is plotted on the vertical axis, and the time is plotted on the horizontal axis;
To determine how long it took Henry to run 100m; The point corresponding to 100m is traced downward from the line of the graph and we find out that;
It takes Henry 20seconds to run 100m
b) Henry's average speed over the race is simply;
The slope of the distance-time graph.
Therefore,
- Average speed = (100-0)/(20-0)
Therefore, Henry's average speed over the race is; 5m/s.

Ignoring air resistance, the fall has no effect on its horizontal speed. Traveling horizontally at 150 m/s for 25 seconds, it'll cover
(25) x (150m) = 3,750 meters
