A mountain goat was traveling down a hill at 1 m/s and then fell off a cliff and was falling at the acceleration due to gravity 9.8m/s2. What was its final velocity if it fell 54 meters to t 1. A bicyclist accelerates at 0.89 m/s2 during a 5.0-second interval. What is the change in the velocity of the bicyclist and the bicycle?

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
