- A van travels a distance d=28 m in the positive x-direction in a time of t=19.5 s. The van immediately brakes and comes to rest in t2=6 s. What are the van's average velocity in the horizontal direction, in meters per second, during t1? What was the acceleration, in meters per second squared, during time interval t1, assuming the van started from rest and moved with a constant acceleration? What was the van's instanteous velocity in the horizontal direction, in meters per second, when it began braking? Using the result from part (c), what was the van's horizontal component of acceleration, in meters persocod squared, during the braking period?Can i get help step by step with this problem?Please answer all parts or leaves for someone else.
- Which of the following is a motion diagram between t = 5.00 s and t = 9.00 s? a. options in atttachemnt b. What is the acceleration between t = 5.00 s and t = 9.00 s? If the acceleration is to +x-direction, enter a positive value and if the acceleration is to –x-direction, enter a negative value. anser in m/s^2A motorcycle begins at rest at t0 = 0 seconds. The motorcycle starts moving, and eventually covers a distance d = 840 m, in a time tf = 189 s. In a coordinate system with north being the positive x-direction, the motorcycle's motion is in the northern direction (see figure). 1. What was the motorcycle's average velocity in in the northern direction vavg,N, in this period in meters per second? 2. If the motorcycle's final velocity at tf was 12 m/s, what was the motorcycle's average acceleration in the northern direction, aavg,N, during this period in m/s2?At the end of a (straight) 100 m race, a runner decelerates from a velocity of 9.00 m/s at a rate of 2.00 m/s2 If the origin is back at the starting line, and race was run in the +x direction, write expressions for x(t) and vx(t). Take t=0 to be the moment the runner finished the race and began to slow down. Don’t solve anything
- A car accelerates from rest at 5 m/s2 for 5 seconds. It moves with a constant velocity for some time and then decelerates at 5 m/s2 to come to rest. The entire journey takes 25 seconds. Plot the velocity-time graph of the motion and describe the shape of the graph.A roly-poly bug moves on the x axis. The bug has a variable velocity which is denoted by 2 v = t² - 2.50t.t is time in seconds and v is meters per second. The origin of the roly-poly bug is at t=0. Your job is to figure out the following after 3s have passed. Be sure to use the correct amount of sig figs! a) Velocity of the bug b) The bugs acceleration c) The bugs position THIS IS How I ROLLA cheetah uses a non-constant acceleration to go from 10 m/s to 25 m/s after 5 seconds. Choose all the following statements that are correct. Than The average acceleration is 3 m/s2. We have enough information to find the distance traveled during this 5 seconds. You can't determine the average acceleration because acceleration is not constant. We have enough information to find the average velocity.
