A car is in a drag race where it accelerated from rest at 3m/s^2 until it reaches it maximum velocity. The race is 100m long.

Part A: If the car reaches its maximum velocity after 5 seconds, what is the cars maximum velocity.

Part B: How fat has the car travelled when it reaches it maximum velocity?

Part C: As the race is 100m long, how long does it take for the car to reach the finish line?

Answer #1

Hence maximum velocity reached after the five seconds is 15m/s

C) We know,

Displacement,S= ut+1/2 at​2

H​​​​​ence distance travelled till the maximum velocity reached is 37.5metre.

He​​nce time to cover 100m is 8.1 seconds

A sprinter runs a 100 metre race. He does not move for 0.2 seconds after the starting pistol is fired. Then his velocity vms-1 increases as v(t) = -0.5t2 + 5t - 0.98 where t is time in seconds. he reaches his maximum speed and maintains this until he crosses the finish line. Calculate his time to complete the race.

A car travels along a straight road. It starts from rest and accelerated in two stages. Each stage takes the same amount of time. In the first stage, the car speeds up with acceleration 3.0 m/s^2. At the end of the second stage, the cars velocity magnitude is 2.5 times greater than it is at the end of the first stage. Find the acceleration magnitude in the second stage.
