Astudent is her teacher move a 9.5 kg box of books. what net sideways force must she exert on the box to slide it across the floor so that it accelerates at 1.0 m/^2?

Mass of the box which contains books (m) = 9.5 kg

Acceleration required (a) = 1 m/s^2

Let the force applied by the teacher and student be F.

The only force acting in the horizontal direction is F and it will produce an acceleration of 1 m/s^2

According to Newton's Seconds law:

F(net) = ma

F = ma

F = 9.5 × 1

F = 9.5 Newtons

Hence, the sideways force applied by teacher and the students is equal to 9.5 Newtons

i think it would be 80 km/h because 30 + 50 = 80 (sorry if this not the right answer i'm trying my best)

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.
