Constant Acceleration Problems

1. A cyclist is traveling at 12.0 m/s when he applies the brakes and begins to slow. After 4.5 s the cyclist has slowed to 3.0 m/s. What was the cyclist's (a) acceleration (assume it was constant)?, and (b) the distance traveled in this time?
2. A truck driver travels at 90.0 km/h down a highway when he sees a deer cross in front of him down the road. He hits the brakes with a reaction time of 0.750s and begins to slow down (at a constant rate) of 5.50 m/s Reacting to the horn, the deer yielded and the truck driver was able to disengage the brake- his speed at that time was 45.0 km/h. a) How far from the moment he saw the deer to when the brakes were disengaged did the truck travel? b) How long was the truck braking?
3. How long does it take an airplane, accelerating from rest at 5.00 m/s2, to travel 360 m?
4. A body moving with uniform acceleration has a velocity of 11.S cm/s when its X coordinate is 5.0 cm. If its × coordinate 6.0 s later is -5.0 cm, what is its acceleration?
5. The initial velocity of a body is 4.60 m/s. What is its velocity after 5.50 s if it (a) accelerates uniformly at 3.00 m/s2; and (b) accelerates uniformly at -3.00 m/s2?
6. A jet plane lands with a velocity of 115 m's and can accelerate at a maximum rate of -5.25 m/s2 as it comes to rest. a) From the instant it touches the runway, what is the minimum time needed before it comes to rest?
b) Can this plane land on a small tropical runway airport where the runway is 0.950 km long? If Yes - how much room to spare, if No how much more needed?
7. A body is traveling at 18.0 m/s and comes to rest after undergoing a uniform negative acceleration for 40.0 m. a) What is the acceleration of this body? b) How long does it take to come to rest?
A car enters a tunnel at 24 m/s and accelerates steadily at 2.0 m/s2. At what speed does it leave the tunnel, 8.0 s later?
for 8.00s
; 33.8 m 2. 61.4 m ; 3.02 s 3. 12 s 4. -4.4 
5. 21.1 m/s ; -11.9 m/s 6. 21.9 s ; no, it reeds 1.26 km to land.
