Question

The wheels on the 1500 kg car generate the friction force F described by the graph. If the car starts from rest, determine its speed (in m/s) when t = 6 seconds.

Please use four significant figures in the final answer.

Thank you! :)

soli Cruis M = 1500kg F(KN) ~ 2 2 6 tlo area under fort force us time give the mong momentum AI= triangle Area = AltA2 = 1 bh, - 1x2x6 + 4x6 2 = 122x6 6+24=30 KN-S. momentum = mv. A2= rectangle - ban, - 426 mu= Area. 1500 kN= 30 x 103 N-s. N-S = kg 3. N-s V= 304103 Isoo ks AS V= 20mis The speed of canuonis
