A car starts from rest and accelerates uniformly to attain a velocity 20 m/s after 5s. The average velocity of the car is 10 m/s.
A car starts from rest and accelerates uniformly at the rate of -1m/s1 for 5sec. It the maintains rhe velocity for 30 s. then the brakes are applied and the car is retarded to rest in 10 s. Find the maximum velocity attained by the car and the total distance travelled by it.
Draw a velocity-time graph to show the following motion :
A car accelerates uniformly from rest for 5 s; then it travels at a steady velocity for 5 s.
