To the nearest tenth of a mis what is the average speed? 2. What is the runner's average velocity in the previous problem? 3. A car accelerates at a constant rate from zero to 33.5 m/s in 10 seconds and then slows to 16.4 m/s in...
A car accelerates from rest at S m/s for 5 seconds. It moves with a constant velocity for 15 seconds, and then decelerates at 5 m/s to come to rest in 5 seconds. The entire journey takes 25 seconds. Plot the velocity-time graph of the motion AND determine the total distance the car travelled. (10 pts.) 4.
1 (a) A car accelerates from rest to a speed of 10.9 m/s in 8.4 seconds. Find the magnitude of the average acceleration. (b) If I accelerate for 5.3 seconds in my car at 2.6 m/s2 when I have an initial velocity of 20.9 m/s, what final velocity do I have? (c) If I apply an acceleration in the opposite direction to my initial velocity for 7.4 seconds of -3.2 m/s2 when I have an initial velocity of +21.6 m/s,...
A dolphin swims at a constant velocity of 15 m/s southeast for 10 seconds, slows to a stop at a rate of 3 m/s^2, and then accelerates northwest at a rate of 2 m/s^2 for 5 seconds. (a) sketch the acceleration as a function of time; (b) find an expression for the dolphin's average velocity over any time interval [0,t] during the motion; (c) find the expression fo the dolphin's displacement as a function of time; and (d) sketch the...
A car starts from rest at a stop sign. It accelerates at 4.0 m/s2 for 9 seconds, coasts for 4 s, and then slows down at a rate of 3.0 m/s2 for the next stop sign. Howfar apart are the stop signs?
A car accelerates at 5 m/s^2 for 8 seconds. The direction of its acceleration is due east. If its initial velocity was 7 m/s, also due east, what is its speed during this time interval? Round your answer to the two decimals. ________ A car accelerates at 7 m/s^2 for 2 seconds. The direction of its acceleration is due east (east = positive direction). If its initial velocity was 47 m/s, due west, what is its final velocity? Round your...
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 bus accelerates at 1.7 m/s from rest for 13 s. It then travels at constant speed for 22 s, after which it slows to a stop with an acceleration of magnitude 1.4 m/s2. (a) What is the total distance that the bus travels? km (b) What was its average velocity? m/s eBook
