Question

A certain force exerted for 1 2 seconds raises the speed of an
object from 1 8 ms to 4 2 ms find the accerleration ,if mass of the
object is 5 5 kg calculate the force applied

Dear Student ,
Here in this case the acceleration of the object is ,
a=v-ut=4·2-1·81·2=2 m/s2Now the mass of the object is 5·5 kg so the applied force is ,F=ma=5·5×2=11 N
