A constant force acts on a body of mass 0.9 kg at rest for 10 s . If the body moves a distance of 250 m , the magnitude of the force is
Text Solution
Verified by ExpertsThe correct answer is:
D
v 0,5 250 m, t 10 sec
\(s = ut + \frac{1}{2} at^{2}\) ⇒ ⇒ \(250 - \frac{1}{2} a (10)^2 = a - 5 m/s^2\)
So, \(f = \mu n = 0.9 \times 5 = 4.5\,N\)
