Question

A force of 100 N acting on a object of mass 50 kg changes its velocity from 18 km/h to 72 km/h. Calculate the distance covered by the object in this time interval

Answer 1

Answer:

F=ma

100=50×a

2m/s=a

v=u+2as

77×5/18=18×5/18+2×2×s

21=5+4s

21-5=4s

16/4=s

4m is the distance travelled (approx)
