Speed of rock before impact is 50 m/s
Given that;
Time taken by rock from bridge = 5 seconds
Find:
Speed of rock before impact
Computation:
Initial velocity = 0 m/s
Using first equation of motion
v = u + gt
v = 0 + (10)(5)
v = (10)(5)
v = 50 m/s
Final velocity = 50 m/s
Speed of rock before impact = 50 m/s

Step-by-step explanation:
Answer:
849.7m2
Step-by-step explanation:
L= length
SA = surface area
volume = L x L x L
1700= L x L x L
find cube root
=11.93m
round off to 1 dp
=11.9m
SA= 6( L x L)
= 6( 11.9 x 11.9)
=6(141.61)
=849.66m2
round off to 1 dp
=<u>849.7m2</u>
Theres always 180 degrees in a flat line angle thingy you need answers fast so im not looking up what its called but 180-125=55 and then you 55-1=54 then 54/3=18!!!!!
