Can u explain your question?
Answer:
Distance is 5.0 km and displacement is 0 km.
Explanation:
The diagram is shown below.
Distance is the total length that the truck covers along the complete journey. The truck moves from a stone quarry covering a length of 2.5 km and then again come back to the same point and thus covering another 2.5 km. Therefore, the total length covered by the truck is the sum of forward and backward paths which is equal to 5.0 km.
Now, displacement depends only on the initial and final position. It is given as the difference of final position and initial position. So, the truck starts from stone quarry and returns back to the same position. So, the initial position and final position is same. Therefore, the difference is 0 and hence displacement is zero.
However here coefficient of friction is not given so unable to calculate.
You can calculate it by below formula.
The formula given by

Or

u is coefficient of friction
N is normal reaction.
Here..
box doesn't move means the force if limiting friction is greater than applied force.
Answer:
Aim directly at the monkey
Explanation:
Despite the mass differences, both the monkey and the food will experience the same acceleration hence while the food follows a projectile path, it will then fall and hit the monkey hence achieving the aim of feeding it. You don't need to aim below or above, aim it directly.
