A car starts from rest and accelerates uniformly at xm/s^2 until it reaches a final velocity of 60m/s in 23s. It is then brought to rest for further 15s.
I. Sketch the v-t graph
Ii. Find the value of x
III find the distance travelled during the acceleration
2. A spiral spring of unstreched length 5.0*10 raise to power -2m is clamped vertically on a rigid horizontal support. It's length extends 5.5*10 raise to power-2m when a load of 0.2N is hung on it's free end. What additional load is required for the spring to acquire a length of 6.5*10 raise to power -2m?
