A 2 m wide truck is moving with a uniform speed v0=8 m/s along a straight horizontal road. A pedestrian starts to cross the road with a uniform speed v when the truck is 4 m away from him. The minimum value of v so that he can cross the road safely is2.62 m/s4.6 m/s3.57 m/s1.414 m/s

A car of length 1 m is moving on a straight road with a uniform velocity of 20 m/s. Initially the front of the car is 100 m behind the rear end of a truck of length 15 m. The truck and the car are moving in the same direction. Truck has a uniform speed of 10 m/s. Find the time taken for the car in seconds to travel from the initial point to completely pass the truck.6 s8.8 s11.6 s5.9 s
