Question

mass of a body is 2kg and slides on a table with velocity of 4m/s and a frictional force of 2N..what is the force required to keep the body moving with that uniform velocity​

Answer 1

Answer:

40 kg is correct answer

Answer 2

Explanation:

HEY MATE .........

$a\implies \: b \\ \\ u = 4m |sec| \\ v = 0 \\ \\ t = 2sec \\ \\ a = ..... \\ \\ v = u + at \\ \\ 0 = 4 + a(2) \\ \\ a = - 2m {s}^{2} \\ \\ \\ so \: force = ma \\ \\ \implies2 \times 2 = 4n$
