<u>1) 187.5ms^2</u>
<u>1) 187.5ms^22) 307.5m</u>
Step-by-step explanation:
1) You can use the formula:
Force = Mass x Acceleration
750 = 4 x a
750 = 4a
750/4 = a
<u>187.5ms^2</u>
2)
For every one second it travels 12.3 meters therefore you can just do 12.3x25 = 307.5m
Percentage change = 100((New Value - Original Value) / Original Value)
So....
100((800 - 1000) / 1000)
= 100(-1/5) = -20%
Considering the question asks what is the percentage <em>'decrease'</em> and thus has mentioned that the price is decreasing, you should just give the answer as 20%. If it was not mentioned that the value increases or decreases, it would be correct to put it as -20%
