A 650 N student is Rollerblading at a velocity of 7.8 m/s [W] when the student trips and slides horizontally along the trail, coming to a stop 0.95s.

Question

A 650 N student is Rollerblading at a velocity of 7.8 m/s [W]  when the student trips and slides horizontally along the trail, coming to a stop 0.95s.

Determine the students average acceleration

Henry · Answer

a = (v-Vo)/t. a = (0-7.8) / 0.95 = -8.21 m/s^2.
