- An object goes from a standing start through 324 m in 7.40 s. (a) What constant acceleration does it experience?In 15 seconds, an automobile accelerates from rest to 48 miles per hour. For the first six seconds, the acceleration increases consistently with time until it reaches a constant value. After 6 seconds, what is the velocity? in m/sFather drove 176km in 7 hours. For the first 92km, he spent for 4 hours. What was his average speed for the remaining journey? k(m)/(h).
- A car has acceleration of 1.20 m/s2 and starts from 2.50 m/s. What is its speed after 5.00 seconds, in m/s? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed.A motorist with an expired license tag is travelling at 10.0 m/s down a street, and a policeman on a motorcycle, taking another 5.00 s to finish his donut, gives chase at an acceleration of 2.00 m/s2.
