Ok, in calculus right now we are working on integrals. I cannot figure out how to do these word questions with velocity and acceleration in them. Can someone please show me how?
1. A car is moving along a straight flat road at a velocity of 90 km/hr. The driver applies the brakes so it decelerates at 10 m/s^2. How long will it take to stop? How far will the car travle from the time the brakes are applied?
2. An object is moving along a streight line with its position messured relitive to a fixed point O. The velocity of the object at any time is v(t)= 3t^2 cm/s. Initaily the object is 8 cm to the left of the point O. Deturmine the objects accseleration when it is at O.
3. A ball is dropped from the 553 m tall CN tower in toronto. What is the velocity of the ball when it hits the ground?
