12) A 300 kg automobile is travelling at 36 kmph,the average resistive force needed to stop it in 1 minute is(A) 250N(b) 500 N(c) 750 N (d) 1000N​

Answer» FORCE Explanation:Resistive Force = ∆ P / t [ Velocity = 36 kmph × 5 / 18 = 10 METRE / second ] [ ∆ P = MASS × velocity ] Resistive Force = m × v / t = 300 × 10 / 60 seconds = 300 / 6 ★ Force = 50 Newton ★
