A massive steel cable drags a 20.0 kg block across a horizontal, frictionless surface. A 90.0 N force applied to the cable causes the block to reach a speed of 3.60 m/s in 2.40 s.
What is the difference in tension between the two ends of the cable?
The Attempt at a Solution
a=3.6/2.4= 1.5 m/s2
Just looking at the numbers it doesnt look right
Thanks all for your help
