Answer» 10 N in the opposite direction of motion.Explanation:Hi FRIEND!First, let us find acceleration of the BLOCK. We can calculate force later by the formula Force = MASS x accelerationTo find acceleration, let us use the equation of motion v^2 - u^2 = 2asHere, u = 10, v = 0 , s =5-100 = 10 a ==========> a = -10 m/s^2 (or) 10 m/s^2 in the opposite direction of velocity.Force = mass x acceleration = 1 x 10 = 10 N in the opposite direction of motion.Hope it helps!!! |
