In order to find the force (F), you would have to use the formula for it:
F=ma
where m is mass and a is acceleration.
In the problem, the mass is 2.85kg and the acceleration is 4.9m/s^2.
Therefore,
F=2.85kg(4.9m/s^2)
F=13.965kg(m/s^2)
Since N=kg(m/s^2)
F=13.965N
And because the problem requires that we use only 2 significant figures,
F=13N
Therefore, the student must exert 13N of force.
Distance of first instance = speed * Time
= 60 * 3 = 180 miles
Distance of second instance = speed * Time
= 24 * 5 = 120 miles
So, Total Distance = 180 + 120 = 300 miles
In short, Your Answer would be 300 miles
Hope this helps!
