Atruck traveling at a constant speed of 28 m/s passes a more slowly moving car. the instant the truck passes the car, the car begins to accelerate at a constant rate of 1.2 m/s^2 and passes the truck 545 m farther down the road. what was the speed of the car (in meters/second) when it was first passed by the truck?

the velocity of car when it passes the truck is u = 16.33 m/s

Explanation:

given,

constant speed of truck  = 28 m/s

acceleration of car = 1.2 m/s²

passes the truck in 545 m

speed of the car when it just pass the truck = ?

time taken by the truck to travel 545 m

              time =

              time =

              time =19.46 s

velocity of the car when it crosses the truck

u = 16.33 m/s

the velocity of car when it passes the truck is u = 16.33 m/s

what was the acceleration of the 2 kg cart?

⇒ 16.0 cm/s2

what was the acceleration of the 4 kg cart?

⇒ 8.1 cm/s2

what was the acceleration of the 6 kg cart?

⇒ 5.3 cm/s2

the answer is b i think
