Determine the acceleration of the cart. Neglect the mass of the wheels Express your answer to three significant figures and include the appropriate units The cart and its load have a total mass of 130 kg (Figure 1) a-Value Units Figure Submit Request Answer 1 of 1 100 N Part B Determine the normal reaction on the pair of wheels at A. Neglect the mass of the wheels Express your answer to three significant figures and include the appropriate units. 1.2 m 0.5 m NA-Value Units 0.3 m 0.4 m0.6 m Submit Request Answer

Part A has been found to be 0.615 m/s^2.

Parts B and C have been found NOT to be 598 N and 736 N respectively. If you get these answers, please try again.

Thank you!

Answer 1

Given data Total mass (m) = 130 kg Now draw the pree body diagram as shown below from the above triangle sin theta = 3/5 sin theta = 0.6 cos theta = 4/5 cos theta = 0.8 Now Sigma f_y = 0 N_A + N_B = m g + 100 sin theta From the above diagram N_B = 669 N = > part - C Normal reaction on the pair wheel at B is then N_B = m g + 100 sin theta - N_B = 130 times 9.81 + 100 times 0.6 - 669 = 1335.3 -669 Normal reaction on the pair wheel at A N_A = 666.3 N = > part - B part - A Now calculating the acceleration of the cart a = 100 cos theta/m a = 80/130 acceleration a = 0.6154 m/s^2
