When traffic light turns green, the driver of a high performance car slams the pedal into high speed. Thespeedometer shows 25.0 ms-1 of speed. Calculate this reading to km min-1

A car is stopped at traffic lights. When the light goes green, the car accelerates and goes from a velocity of 0m/s to 20m/s in 5s. Calculate the cars acceleration.

As soon as a traffic light turns green, a car speeds up from rest to 50.0 mi/h with a constantacceleration of 9.00 mi/h/s. In the adjoining bicycle lane, a cyclist speeds up from rest to 20.0mi/h with a constant acceleration of 13.0 mi/h/s. Each vehicle maintains constant velocity afterreaching its cruising speed. (a) For what time interval is the bicycle ahead of the car? (b) By whatmaximum distance does the bicycle lead the car?

A train of length 60 meters is running with a velocity of 20 m/s.  The engine driver sees that a signal post 440 meters is red, but before he pulls the brakes it turns green and so the trains maintain its velocity.  Find the time the train takes to pass the signal post.

In a race, average speed of total 75 bikes is 35km/hr.The average speed of red bikes is 55 km/hr. If average speed of green bikes is 30km/hr, then how many green bikes are there?

A car travels the first 50 km at a uniform speed of 25 kmph and the next 60 km at a uniform speed of 20 kmph. Calculate the average speed of the car in kmph
