Truck and mass-pulley system: |dw:1378890844496:dw| At the instant shown, the velocity and acceleration (with positive defined to the right), are: Vt=11.9m/s and at=1.4m/s/s The angle of the cord to the horizontal is β=39.9 degrees. g=9.8m/s/s, mass of block=87kg, mass of truck=2.08 tonnes a) What is the tension force T in the cable at this instant? b)What is the net horizontal thrust force required to produce the truck's motion? This includes drive force from wheels, rolling resistance and air resistance.
