An object has an average acceleration of + 6.18 m/s2 for 0.266 s. At the end of this time the object's velocity is + 9.90 m/s.

Calculate the magnitude of the acceleration of a sled that is heading down a 39° slope (one that makes an angle of 39° with the horizontal). The coefficient of kinetic friction on ice is μk = 0.100.

What is the name of the device that measures how loud a sound is?

The static friction force is the force needed to keep an object moving at a constant velocity across a surface. the force needed to bring an object to rest. (incorrect) the minimum force required to overcome static friction and move an object.
