I am having trouble calculating uncertainty when a number is added to a value with uncertainty.

M = 350g

a = 0.624 [itex]\pm[/itex] 0.001

µk = 0.07

g = 9.80 m/s2

2. Relevant equations

T = M*a + µk*M*g

3. The attempt at a solution

T = (350g)*(0.624 m/s2) + (0.07)*(350g)*(9.80m/s2)

T= 458.5 N

D[itex]_{}t[/itex] = M*(D[itex]_{}a[/itex]) + ......

D[itex]_{}t[/itex] = (350g)*(0.001 m/s2) + ......

D[itex]_{}t[/itex] = 0.35 N + ....
