A car accelerates from rest with a constant acceleration of 1.5m/s^2 for 14 seconds . the car then continues traveling at the constant velocity with the speed it achieved after the 14 seconds of acceleration . it travels at this constant velocity for an additional 25 seconds. how far did the car travel during this whole motion?
A particle, starting at rest, accelerates at 5 m/s2 for 10 s. It then decelerates to 30 m/s over a period of 10 s. The particle then moves at a constant speed for 20 s before decelerating to zero over a period of 5 s. 6. (12 points) A particle, starting at rest, accelerates at 5 m/s for 10 s. It then decelerates to 30 m/s over a 0 s. The particle tl of 5 s Plot the velocity and...
A car in stop-and-go traffic starts at rest, moves forward 21 m in 8.0 s, then comes to rest again The velocity-versus-time plot for this car is given in the figure (Figure 1). Part A What distance does the car cover in the first 4.0 seconds of its motion? Part B What distance does the car cover in the last 2.0 seconds of its motion? Part C What is the constant speed V that characterizes the middle portion of its...
Prob. 2 A car starts from rest, accelerates at 1.5 m/s, and reaches a maximum speed vi. After that it decelerates at 2 m/s until it stops. During the entire process the car has traveled a distance of I km. (a) Sketch the velocity diagram of the particle during the process. (Leave vI as an unknown on the diagram) (b) Determine the maximum speed vi. (e) Determine the total time required.
A car starts from rest, then accelerates at a constant rate over a distance of 54 m. It then immediately decelerates at a constant rate over a distance of 103 m. The entire trip lasts a total duration of 12.7 s. What were the magnitudes of the car s accelerations for the speedup and slowdown stages respectively?
A particle, starting at rest, accelerates at 5 m/s2 for 10s. It then decelerates to 30 m/s over a period of 10s. The particle then moves at a constant speed for 20s before decelerating to zero over a period of 5s. Plot the velocity and acceleration of the particle as functions of time. What is the total distance traveled by the particle?
A car starts from rest, then accelerates at a constant rate over a distance of 69 m. It then immediately decelerates at a constant rate over a distance of 133 m. The entire trip lasts a total duration of 25.7 s. What were the magnitudes of the car s accelerations for the speedup and slowdown stages respectively? a) 0.61 m/s^2, then 0.61 m/s^2 b) 5.18 m/s^2, then 2.68 m/s^2 c) 1.79 m/s^2, then 0.93 m/s^2 d) 2.68 m/s^2, then 5.18...
A car going 5 m/s accelerates at 2 m/s^2 for 3 seconds. Then he travels at a constant velocity for 4 seconds. What is the total distance traveled in the 7 seconds and what is the final speed of the car?
A bus starts from rest and accelerates uniformly for 20 seconds to a speed of 18 km/h. It then moves with a uniform velocity and it is finally brought to rest in 100 meteres with a constant retardation. If the total distance travelled is 0.5km. Find the accelration, retartdation and total time taken. My answers are total time = 110s Retardation -1/4ms^-2. Please check if they r correct or not!!!
A prairie dog initially at rest, accelerates at a constant rate of 0.2 m/s^2 east for 10 seconds. (a) sketch the velocity as a function of time during the motion. (b) find an expression of the prairie dog's average velocity over an interval [0,t] during the motion. (c) find an expression for the prairie dog's displacement as a function of time during the motion. (d) sketch the displacement as a function of time for the entire motion.
