Question

Round off answers to the nearest hundredths. Show all solutions. A force of 80 N gives an object of unknown mass and acceleration of 22 m/s^2. What is the mass of the object? A 25 N box is pulled vertically upward by means of a cord. Find the acceleration of the box if the tension in the cord is 35 N. A 50 kg box rests on a smooth frictionless table. Connected to the box is a light string passing through a pulley at the end of the table. Suspended on the other end of the string is a 20 kg box. Find the a) acceleration of the system; b) the tension in the string, and c) the displacement 15 seconds after starting from rest.

Explanation / Answer

here,

1)

force , F = 80 N

let the mass of object be m

accelration , a = F/m

22 = 80 /m

m = 3.64 kg

the mass of object is 3.64 kg
