A .45kg piece of putty is dropped from a height of 2.5m above a flat surface. When it hits the surface, the putty comes to a rest in .30s. What is the average force exerted on the putty by the surface?
V=d•t
F=m•a
a=v/t
Here is a question:
Jane and John with masses of 51kg and 62kg respectively, stand on a frictionless surface 13m apart. John pulls on a rope that connects him to JAne, giving jane an acceleration of .92 m/s*s toward him. a. What is Johns acceleration?? b. IF the pulling force is applied...
After rereading the caption in the book, I am not so sure it would slow down or stop. The perpendicular may have no effect on the motion of the object at all.
Describe the motion of an object that is initially traveling with a constant velocity and then receives an acceleration of constant magnitude a) in a direction parallel to the initial velocity, b) in a direction perpendicular to the initial velocity, and c) that is always perpendicular to the...
