A 1.20kg object is placed on a smoothe level table and is attached to a hanging mass using a light string over frictionless pulley in a Fletcher's trolley arrangement. The 1.20kg object accelerates along the table at 2.31m/s^2 while the hanging object accelerates down at...
A 1000kg car is travelling at 27.0 m/s. Determine the force required to stop it in 70.0 m.
The Attempt at a Solution
I attempted to treat this question as if I knew how many seconds it took to stop, and did this:
70.0m / 27.0m/s = 2.59259s
2.59259s / 27.0m/s = 0.096...
