Expert Answer:

F o r c e space i s space g i v e n space a s space F space equals space minus open parentheses fraction numerator d U over denominator d x end fraction i space plus space fraction numerator d U over denominator d y end fraction j space plus space fraction numerator d U over denominator d z end fraction k close parentheses
p u t t i n g space t h e space v a l u e space o f space f r o m space q u e s t i o n comma space i n space q u e s t i o n space t h e r e space i s space n o t space a n y space c o m p o n e n t space a l o n g space z space a x i s space space s o space fraction numerator d U over denominator d z end fraction equals 0
s o space F space equals space 7 fraction numerator d x over denominator d x end fraction i space minus space 24 fraction numerator d y over denominator d y end fraction j
F space equals 7 i minus 24 j
a s space w e space k n o w space a c c e l e r a t i o n space a space equals space F over m
s o space a space equals space fraction numerator 7 i minus 24 j over denominator 5 end fraction equals space 7 over 5 i space minus space 24 over 5 j
t a k i n g space t h e space m a g n i t u d e space o f space a c c e l e r a t i o n space w e space g e t
a space equals square root of 49 over 25 plus 576 over 25 space end root
a equals square root of 625 over 25 end root
a space equals space square root of 25
a equals space 5 space m s to the power of negative 2 end exponent
