Making use of this table, determine the following Aluminum Copper Steel (a) the acceleration of the two blocks 6.72 Your response differs from the correct answer by more than 100%. m/s* (b) the tension in the string 7.39 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. N Need Help?

a= m2g(sin 35 - UKcu cos35) - m1gUKAl / m1+ m2
a= 9.80665[6.9 kg (sin35- .36cos35)- 1.1 x.47 / 1.1+6.9
a= 9.8066[6.9(.573576-.36x.81915) - 0.517 ] / 8
a= 9.80665[6.9(0.278686)- 0.517]/8 = 1.72347m/s^2
b-T = m1a + uk. m1g = 1.1kgx 1.72347m/s^2 + .47 x 1.1 x 9.80665
T = 1.895817 +5.07003805= 6.96585505 N
