Answer:
gravity pulls the falling object to the ground
Explanation:
<u>13788 J is required to finish the work.</u>
Explanation:
Given that,
Mass of lawnmower is 20 kg
Force = 30 N
Displacement ( distance moved )= 20m
The force of 30N is applied along the direction of motion and was applied for the whole 20 m.
The formula of work done for one pass is
Substituting the given data into the formula,
W = 459.6 J
Work done for one pass = 459.6J
Now, work done for 30 passes is calculated by multiplying the work done for one pass into 30.
Work is done by the person pushing the mower to finish the work is <u>13788 J</u>.
The snapshot of light as the cart moves with constant velocity is represented by a graph with uniform displacement at each time interval.
The change in displacement with time is uniform at constant velocity. The displacement of the supplied moving item grows at the same pace.
The beginning velocity equals the ultimate velocity at constant velocity.
v₁ = v₂
The object's acceleration at constant velocity is zero since the velocity change with time is zero.
As a result, we may deduce that the graph with equal displacement at each time interval reflects a snapshot of light as the cart moves at a constant speed.
A moving object's displacement-time graph shows the distance traveled by a moving item as time passes. A vector quantity is displacement. The slope or gradient of this graph represents the velocity of the item. The displacement-time graph, also known as the position-time graph, describes an object's motion. In this graph, the displacement of the moving item is displayed on the y-axis as a dependent variable, while time is shown on the x-axis as an independent variable.
