Since the force 235 N is at an angle, you want it to be parallell with the ground. To do that you do the cosine of the angle multiplied by the force. So 235*cos34.8 = 192.97 N Using F=ma 192.97=19a so a= 10.1563 m/s^2

To find the product of two fractions, you simply multiply across top & bottom. But first, you can see that 12 and 15 have a common factor of 3. So, (11 / 15) * (12 / 7) then becomes: (11 / 5) * (4 * 7) Multiplying straight across, you get: (11 * 4) / (5 * 7) = 44 / 35
