- A car starts from rest with an acceleration of 5.3 m/s² which decreases linearly with time to zero in 10.3 seconds, after which the car continues at a constant speed. Determine the time t required for the car to travel 330 m from the start. Answer: t = i ! SA car starts from rest at t = 0 s, and speeds up with a constant acceleration of 1.81 m/s2 for 6.00 s. Then it continues with a uniform speed for another 6.00 s. Finally, it speeds up with a constant acceleration of 2.02 m/s2 until it reaches a speed of 18.0 m/s. (a) Draw the velocity vs. time and acceleration vs. time graphs for this motion. Numerical values on the graphs are not required. (b) How long does it take for the car to reach a speed of 18.0 m/s? Time is measured from the beginning at t = 0 s (c) What is the total displacement of the car?A vehicle accelerates down an on ramp and eventually reaches highway speed. The position of the vehicle is described by the following equation:x(t) = At2/(t+B) write an expression for the vehicles instantaneous velocity as a function of time
- A car starts from rest. It accelerates at constant acceleration for 5.0 seconds during which the car covers a distance of 125 m. After that the car continues at that speed for 22 seconds, after which the car slows down at a constant deceleration of – 4.5 m/sec2 until coming to a complete stop. Draw a v vs t, graph, label all the relevant data, and use the graphical method to determine total distance traveled.A driver is driving uphill. He maintained his throttle, causing his car to constantly decelerate as it is coming up the hill. The road going up the hill is 217 m long and it took him 8.8 seconds to get to the top of the hill. His speed has reduced to 22 m/s at that point. What was the car's acceleration (include a negative sign in your answer)? Hint: the initial position of the car can be set at the origin.Some experimental researcher tells us that the position of an object as a function of time is given by x(t) = at3 - bt2 + ct - d, where the constants are a = 3.6 m/s3, b = 4.0 m/s2, c = 60 m/s and d = 7.0 m. Find the average acceleration over the first 2.4 seconds. A) 18 m/s/s B) 54 m/s/s C)36 m/s/s D) 76 m/s/s
- A car traveling 59.1 km/h is 29.5 m from a barrier when the driver slams on the brakes. The car hits the barrier 2.68 s later. (a) What is the car's constant deceleration magnitude before impact? (b) How fast is the car traveling at impact? (a) Number i (b) Number i Units UnitsThe velocity of a particle moving along the x axis varies according to the expression vx = 40 - 5t, where Vx is in meters per second and t is in seconds. A) Find the average acceleration in the time interval t 0 to t 2.0 s. B) Determine the acceleration at t 2.0 s.You decide to travel by car for your holiday visits this year. You leave early in the morning to avoid congestion on the roads. This enables you to drive at a comfortable speed of v1=67.1 mph for t1=1.70 hours. However, after this time, you unexpectedly come to a stop for tstop=43.8 min. Traffic starts moving again and you finish your travel at v2=55.6 mph for an additional t2=1.40 hours. There are 1609 meters in one mile. What was the total distance d traveled? What was the average speed v?
- Ilya and Anya each can run at a speed of 7.60 mph and walk at a speed of 3.50 mph . They set off together on a route of length 5.00 miles . Anya walks half of the distance and runs the other half, while Ilya walks half of the time and runs the other half. a) Find Anya's average speed. b) How long does it take Ilya to cover the distance? (in minutes) c) Now find Ilya's average speed. ThanksA car accelerates at a constant rate from rest to 16 m/s in a distance of 74 m. What is the magnitude of its acceleration, in m/s2? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.Assume you are driving a car at a constant speed of 76 km/h. Suddenly you see a deer standing on the highway and you must put on the brakes. Your reaction time (time elapsed between the moment you see the deer and your foot hitting the brakes) is 0.118 s. The brakes provide an acceleration with a magnitude of 4 m/s2, and a direction opposite the initial velocity. How do you find the total distance traveled?
