a. Calculate the acceleration required to push a box weighing 3.5 kg with 2 N of force. b. A crate weighing 45 kg was pushed on the floor to about 15 m with a force of 20 N. Calculate the work done.
Answer of (b)
F is the force applied m is the mass on which force acts a is the acceleration produced due to the force We know; F=ma So, a=F/m a=20/2 a=10m/s2
