physics-the-acceleration-of-an-object-is-a-measure-of-how-much-its-velocity-changes-in-a-given-perio

Physics The acceleration of an object is a measure of how much its velocity changes in a given period of time. acceleration $=\frac{\text { final velocity }-\text { initial velocity }}{\text { time }}$ Suppose you are riding a bicycle at 6 $\mathrm{m} / \mathrm{s}$ . You step hard on the pedals and increase your speed to 12 $\mathrm{m} / \mathrm{s}$ in about 5 $\mathrm{s}$ . a. Find your acceleration in $\mathrm{m} / \mathrm{s}^{2}$ . b. A sedan can go from 0 to 60 $\mathrm{mi} / \mathrm{h}$ in about 10 s. What is the acceleration in $\mathrm{m} / \mathrm{s}^{2} ?(\text { Hints: } 1 \mathrm{mi} \approx 1609 \mathrm{m} ; 1 \mathrm{h}=3600 \mathrm{s} .)$

Shown below is a graph of velocity versus time for a moving object. The object starts its motion at x = 0. Figure 1: (a) What is the object's acceleration at t = 1 sec? (2pt) (b) What is the position of the object at t = 1.5 sec? (3pt) (c) What is the acceleration at t = 2 sec? (2pt) (d) What is the distance travelled by the object from t1 = 1.5 sec to t2 = 3.0 sec and its position at the time t2? (5pt) (e) What is the acceleration at t = 4.0 sec? (2pt) (f) What is the final position of the object at t = 5.0 sec? (3pt) (g) What is the average velocity of the object in time interval Δt from t1 = 0 to t2 = 5.0 sec? (3pt)

00:03 Here in the first question, we are given to find acceleration a, whereas the formula for acceleration a is the difference between the velocities with respect to time.
00:17 Here, the initial velocity of the bicycle is 6 meters per second, whereas it is reaching velocity of 12 meters per second within 5 seconds.
00:29 So we have here as 6 over 5, and we got it as 1 .2.
00:36 Where it comes to units.
00:39 So we need to do, so the units of velocity are meters per second, whereas the units of time is seconds.
00:50 So we have 1 .2 meters per second square.
00:55 Now when we go to the second question, we are supposed to find the acceleration of a car with the same formula of the velocities and time.
01:05 Whereas here, the car is starting at a, velocity of 0 miles per hour and is reaching 60 miles per hour within 10 hours...
