18=½m(3)^2 find mass (m)

a rolling ball has 18 joules of kinetic energy and is rolling 3m/s.

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.

What is the percent yield of titanium (iv0 oxide, if 10.2 are formed when 25.7g of titanium (iv0 chloride react?
