Answer is 6.84 approx
reason:-
(2.78^2+6.25^2)^1/2=6.84 approx
Answer:
161.86 N
Explanation:
mass of box m= 55.0 kg
weight of the box, mg= 55×9.81
g here is acceleration due to gravity =9.81 m/sec^2
coefficient of friction between the box and the surface μ= 0.3
the friction force F_s= μmg= 0.3×55×9.81
=161.86 N
to move the ball horizontal force required is 161.86 N
I can't make sense of this question. Julie's throwing the ball, so it's leaving her rather than arriving at her ???
