Hii mate
Here is Ur answer
Mass =5kg
final velocity = 25 m/s
initial velocity = 10m/s
Time taken = 20sec
using first equation of motion
v = u+at
25 = 10+(a)(20). => 15 = 20a => a = 15/20 m/s² = 3/4 m/s²
we know that,
force = mass × acceleration
force = 5kg × 3/4 m/s² => 15/4 N = 3.75 N => force applied
hope this helps
Hope it will help you
