A CONSTAKG BOXNT 25 N F IS APPLIED HORIZONTALLY TO A 34 LG B

A CONSTAKG BOXNT 25 N F IS APPLIED HORIZONTALLY TO A 34 LG BOX STARTING FROM REST. HOW FAR WILL THE BOX SLIDE IN 3.1 S?

WHATS THE NORMAL FORCE ON THE BOX?

Solution

F = 25 N m = 34 kg

a = F/m = 25/34 m/s²

distance covered in 3.1 s = 0.5 x (25/34) x (3.1)² m

= 3.533 m

normal force = mg = 34 x 9.8 = 333.2 N
