A 5.1 kg bucket of water is raised from a well by a rope. If the upward acceleration of the bucket is 3.4 m/s2, find the force exerted by the rope on the bucket.

F=MA
Force = Mass X Acceleration
den
Force=?N
Mass=5.1kg
Acceleration=3.4m/s2
Force=5.1X3.4
=17.34N

tension is the force exerted on the bucket hence by newtons third law, its equal to the force the bucket exerts on the rope.
T - W = 5.1 x 3.4
T = 5.1 x 3.4 + 5.1 x 9.81
= 67.4 N
T = tension
W = weight of bucket

Force = mass * acceleration
In your case:
Force = ( 5.1 kg ) * (3.4 m/s/s) = 17.34 Newtons
