Answer: 0.27 m
Explanation:
The plate slides off the counter with the speed , u = 0.61 m/s in the horizontal direction.
The height of the counter is, y = 0.93 m
The initial speed in the vertical direction is 0 m/s. The plate falls under gravity in the vertical direction.
The time taken for plate to reach the surface is:
y = 0.5 gt²
⇒ t = √0.93 m / √4.9 m/s² = 0.44 s
In the same time, the plate would cover horizontal distance of:
x = u t = 0.61 m/s × 0.44 s = 0.27 m
Thus, the plate falls 0.27 m away from the base of the counter.
Answer:
As arrows
Explanation:
In a free body diagram, the object is treated as a dot and the force is depicted as arrows either moving way from the dot or moving towards the dot.
