At the lowest point in the oscillation,
Explanation:
Since spring block system is performing to and fro motion along straight line
So here we can say at the lowest position of its path the velocity will become zero.
So we can say that momentum of the spring block system is given as
Also we know that after reaching the lowest point the block will again go up towards its mean position
So at the lowest point of the spring block system the block will move upwards again
So this will accelerate upwards hence
Answer:
- 600 J
Explanation:
A (20, 15, 0 ) m
B (0, 0, 7) m
Net force
Work done is defined as
W = -1120 + 450 + 70
W = - 600 J
