f= ma

2N = m*( v-u/t)

2= m*(5-2/10)

2= m*3/10

2*10/3 = m

therefore... m= 6.66 kg

hope it helps...

Answer:

given \: that \ \\ intial \: velocity = v _{i} \:  = 2 \: ms {}^{ - 1}  \\ final \: velocity =   v_{f} =  \: 5 \: m {s}^{ - 1}  \\ time \:  = t = 10 \: sec \\  \: then \\ accesalation \:  = acc. \\  =  \frac{ v_{f} -  v_{i} }{t}  \\  =  \frac{5 - 2}{10}  =  \frac{3}{10}  \: m {s}^{ - 2}  \\ we \: know \: that \\ force \:  = mass \times accesalation \\ f = m \times a \\ then \\  m =  \frac{f}{a}  \\  =  \frac{2}{ \frac{3}{10} }  =  \frac{2 \times 10}{3}  =  \frac{20}{3}  \: kg = 6.66 \: kg
