A car traveling at 28 m/s starts to decelerate steadily. It comes to a complete stop in 13 seconds. What is its acceleration?

Maru [420]

Acceleration = (change in speed) / (time for the change)

change in speed = (speed at the end) minus (speed at the beginning)

change in speed = (zero) minus (28 m/s) = -28 m/s

Acceleration = (-28 m/s) / (13 sec)

Acceleration = -2.15 m/s²

An astronaut on the moon drops a feather from rest (v = 0). The acceleration due to gravity is 1.67 m/s 2 . If the feather beg

olga_2 [115]

Given :

Initial velocity , u = 0 m/s .

Acceleration due to gravity on moon , $g_m=1.67\ m/s^2$ .

Height , h = 2 m .

To Find :

Final position after falling for 1.5 seconds .

Solution :

We know , by equation of motion :

$s=ut+\dfrac{at^2}{2}$

Here , $a = g_m$ .

So , equation will transform by :

$s=ut+\dfrac{g_mt^2}{2}\\\\s=0+\dfrac{1.67\times 1.5^2}{2}\ m\\\\s=1.88\ m$

Therefore , the height form moon's surface is 1.88 m .

Hence , this is the required solution .
