1) set and solve for t
2) , where is the time found in question (1).
3) think about it ... when will -3t have its greatest magnitude?
Q1-A truck with initial velocity 6 m/s^-1 brakes and comes to rest. At time t seconds after the brakes are applied with acceleration a m/s^-2 where a=-3t. This formula applies until the truck halts.
1: Find time taken for the truck to halt.
2:Find distance traveled whilst decelerating.
3:Find greatest deceleration of truck?
Q2-A force of (36-t^2) newtons acts at time t seconds on a particle of mass 1kg. When t=0 the particle has velocity 2m/s^-1 in the direction of the force. Find the velocity of the particle when t=6 and find the distance travelled between t=0 and t=6.
Could somebody please help me out, been stuck for ages Many thanks in advance.
