Problem 6: The rear wheels of the truck shown provide traction force of 2000 N. If the truck has a mass of 1900 kg, determine the its acceleration and the normal force exerted on each pair of front and rear driving wheels. Also, find the time needed for the truck to achieve a speed of 20 m/s starting from rest. The front wheels are free to roll. Neglect the mass of the wheels. -2m-+15m- Problem 7. A wheel has its angular speed increased uniformly. Starting from 15 rad's at t-0 to 70 rad's att 80 s. If the diameter of the wheel is 3 ft, determine the magnitudes of the normal and tangential components of acceleration of a point on the rim of the wheel when -80 s and the total distance the point travels during the time period.
