Answer:
PE = 58.8,J
Explanation:
The potential energy at the top of ramp1 can be found by the application of the formula PE = mgh
Where PE =potential energy
m = mass of block = 2kg
g = acceleration due to gravity = 9.80m/s²
h = height of the top of the ramp from its bottom where the block is initially positioned = 3m
PE = 2×9.8×3 = 58.8J
Answer:
It captures images but does not preserve them.
Acceleration can be any change in speed, increasing or decreasing.
You haven't said whether the ball is speeding up or slowing down.
If its acceleration is positive ... speed is increasing ... then in 2.5 seconds,
it GAINS (0.5 m/s² x 2.5 sec) = 2.5 m/s of speed. Added to its initial
speed of 2.0 m/s, it ends up moving at 4.5 m/s.
If its acceleration is negative ... speed is decreasing ... then in 2.5 seconds,
it LOSES (0.5 m/s² x 2.5 sec) = 2.5 m/s of speed. Added to its initial
speed of 2.0 m/s, it ends up moving at -0.5 m/s. That means that it ends up
moving in the opposite direction compared to its direction at the beginning of
the change.
Answer:
The direction of the displacement is in North-West.
Explanation:
Resultant displacement D is
Here the direction is
Then the direction is 
North-west.
