you are driving your car along a country road ar a speed of 23.8m/s. As you come over the crest of a hill, you notice a farm tractor 25.0 m ahead of you on the road, moving in the same direction as you at a speed of 10.0 m/s. You immediately slam on your brakes and slow down with a constant acceleration of magnitude 8.60 m/s^2. how far will you travel before you stop the car

you are driving your car along a country road ar a speed of 23.8m/s. As you come over the crest of a hill, you notice a farm tractor 25.0 m ahead of you on the road, moving in the same direction as you at a speed of 10.0 m/s. You immediately slam on your brakes and slow down with a constant acceleration of magnitude 8.60 m/s^2. how far is the tractor in front of you when you finally stop?
An inquisitive physics student and mountain climber climbs a 51.0-m-high cliff that overhangs a calm pool of water. He throws two stones vertically downward, 1.00 s apart, and observes that they cause a single splash. The first stone has an initial speed of 2.06 m/s. (b) What initial velocity must the second stone have if the two stones are to hit the water simultaneously?
A roofer tosses a shingle off a 240.1 m high roof, giving it an initial horizontal velocity of 10 m/s. How far from the building does the shingle land? What is the acceleration of the shingle as it leaves the roof at 2m/s^2?
An airplane, starting from rest, move down the runway at constant for 18 s and then takes off at a speed of 60 m/s. What is the average acceleration of the plane?
a parachutist opens his chute at time t=0, while falling vertically at a speed of 50.0 m/s. From the combined effects of gravity and air resistance, he is subject to anupward acceleration of ay= (40/T)e-t/T where T=6.8s. Find the parachutist's speed 10s after the chute is opened and the distance fallen during that period of time.
An ant crawls in a straight line at a constant speed of 0.24 m/s for a distance of 3.0 m, beginning in the corner of a square classroom. It then turns exactly 90 degrees to the right, and proceeds an additional 4.0 m with a constant speed of 0.44 m/s, reaching the other corner of the same wall from which it began. What was the ant’s average speed for the full trip from corner to corner?
A jetliner traveling north is landing with a speed of 74 m/s. Once the jet touches down, it has 755 m of runway which reduced its speed to 11.1 m/s. What is the average acceleration (magnitude & direction) of the jet during landing?
A model rocket rises vertically from rest with a constant acceleration of 3.23 m/s2 until it runs out of fuel at an altitude of 948 m. Neglect air resistance and take upwards as the positive direction for position and velocity. (a) What maximum altitude does the rocket reach? (answer: 1260 m) (b) How much time does the rocket take to reach its maximum altitude? (answer: 32.3 s) (c) What is the velocity of the rocket at the moment it hits the ground? (answer: - 157 m/s) (d) What is the total flight time of the rocket from the moment it is launched until the moment it hits the ground? (answer: 48.3 s)
A wide receiver is running along the sideline straight toward the goal at a constant speed. When he is 27 m away from the goal line he catches the ball, but there is a cornerback 12 m behind him moving with a constant speed of vc = 9.0 m/s. What speed should the wide receiver have to make sure he reaches the goal line just as the cornerback reaches him?
You throw a baseball directly upward at timet=0 at an initial speed of 12.3 m/s. The maximum height is 7.72 m. At what time does the ball pass throughhalf the maximum height?Ignore air resistance and assume g=9.8 m/s
The catapult of the aircraft carrier USS Abraham Lincoln accelerates an F/A-18 Hornet jet fighter from rest to takeoff speed of 173 mi/h in a distance of 307 ft. How much time does it take for the fighter to accelerate to takeoff speed?
A UCI student is running at her top speed of 5.1 m/s to catch a Shuttle bus, which is stopped at the bus stop. When the student is still a distance 42.0 m from the Shuttle bus, it starts to pull away, moving with a constant acceleration of 0.163 m/s2. For what distance does the student have to run at 5.1 m/s before she overtakes the bus?
