I calculated (a)
I don't know how to calculate (b)
Thank you so so so so much! That was so so helpful!DaalChawal said:after integrating both of them you will get this
Can you also pls tell how to calculate 7(c).DaalChawal said:after integrating both of them you will get this
Thank you very much!DaalChawal said:For $0 \le t \lt 1$ $s= 1/2 t^2 + 2/3 t^3$ putting t=1 we get 7/6
For $1 \le t \le 5 $ $v= 30/4 t + 5/4 t^{-2} - 23/4 $ integrate and putting limits we get $x-7/6 = (15/4) (5^2 - 1^2) + (5/4)(1- 1/5)+ (23/4)(1-5)$ I'm getting x =63 + $7 \over 6$ So total distance = 63 + $7 \over 3$ = 65.34
Even I am also not getting the answer may be I made a calculation mistake or the answer is wrong. Afaik this will be done here.
General motion in a straight line is the motion of an object that moves in a single direction without changing its path or speed. This type of motion is often represented by a straight line on a graph.
Uniform motion in a straight line is when an object moves at a constant speed in a straight line, while non-uniform motion is when an object changes its speed or direction while moving in a straight line.
Velocity in general motion in a straight line is calculated by dividing the displacement of an object by the time it takes to travel that distance. It is represented by the formula v = d/t, where v is velocity, d is displacement, and t is time.
Speed is a measure of how fast an object is moving, while velocity is a measure of both speed and direction. In general motion in a straight line, speed is calculated by dividing the distance traveled by the time taken, while velocity is calculated by dividing the displacement by the time taken.
Acceleration is the rate of change of velocity and it affects general motion in a straight line by causing an object to either speed up or slow down. If the acceleration is in the same direction as the motion, the object will speed up, and if it is in the opposite direction, the object will slow down.
