1) A car going at 50km/h slows to a stop when a constant force of 3000N is applied by the brakes. How far does the car travel until it stops? 2) A spring is hanging from the ceiling, When a 100g mass is placed on the spring, the spring stretches by 2cm. What is the spring constant? How far does it stretch with a 150g mass attached to it?
a car traveling 50km/h east accelerates at 0.25 m/s2 west. What will be its velocity and displacement: a) at 3min? b) when it passes it's the initial position?
2. A car accelerates along a straight road from rest to 90 km/h in 5.0s. What is the magnitude of average acceleration in meters per second squared. 3. If you are driving 110km/h along a straight road and look to the side for 2.0s, how far do you travel during this inattentive period? 4. At highway speeds, a particular car is capable of accelerating at about 1.8m/s?. At this rate, how long does it take to accelerate from 80km/h to...
A car accelerates from 10m/s to 30.0 m/s at a rate of 3.00m/s^2. How far does the car travel while accelerating
far must the faster car travel before it has a ro slower car? 11. The cheetah can reach a top speed of 114 km/h (71 mi/h). While chasing its prey in a short sprint, a cheetah starts from rest and runs 45 m in a straight line, reaching a final speed of 72 km/h. the short sprint, and (b) find its displacement at -3.5s (a) Determine the cheetah's average acceleration during hLenath L of a nool in a time t...
5.) A 1000kg The coefficient of friction is .2 How far does the car travel uphill before it comes to rest? car travelling at 20m/s encounters a 200 incline. Distance- booka
(20 points) A car starting from rest travels 220 m in 9.4 seconds with a constant acceleration. It then travels at a constant speed for another 12 seconds. After that, the brakes are applied and the car comes to rest an acceleration of 6.5 m/s2. A) Draw the motion diagram for the entire trip. B) What direction is the acceleration when the car is coming to rest? C) List all known variables with their values. D) What is the acceleration...

A car travels 40 miles in 30 minutes. a. What is the average velocity in kilometers/hour? b. If the car weighs 1.5 tons, what is its kinetic energy in joules (Note: you will need to convert your velocity to m/s)? c. When the driver applies the brake, it takes 15 seconds to stop. How far does the car travel (in meters) while stopping? d. What is the average acceleration of the car (in m/s2) during braking?
