A 310-g air track cart is traveling at 1.25 m/s and a 260-g cart traveling in the opposite direction at 1.33 m/s. What is the sp

UNO [17]

Answer:

$v_{CM}=0.0732\ m/s$

Explanation:

given,

mass of the cart 1, m₁ = 310 g

speed of car 1 , v₁ = 1.25 m/s

mass of cart 2, m₂ = 260 g

speed of cart 2, v₂ = -1.33 m/s

speed of center of mass

$v_{CM}=\dfrac{m_1v_1 + m_2 v_2}{m_1 + m_2}$

$v_{CM}=\dfrac{0.31\times 1.25 +0.26\times (-1.33)}{0.31+0.26}$

$v_{CM}=\dfrac{0.0417}{0.57}$

$v_{CM}=0.0732\ m/s$

Hence, speed of center of mass of the system is equal to 0.0732 m/s

A car undergoing uniform acceleration travels 100 meters from a standing start in a given period of time. If the time were incre

iogann1982 [59]

Answer:

d = 1600 m

Explanation:

If car start from rest and accelerates uniformly then the displacement of the car is given as

$d = v_i t + \frac{1}{2}at^2$

now we know

$d = 0 + \frac{1}{2}at^2$

now if the same car will accelerate from rest for four times of the previous time interval

then we will have

$d = 0 + \frac{1}{2}a(4t)^2$

$d = 16(\frac{1}{2}at^2)$

so the distance will be 16 times more

$d = 1600 m$
