What is the time it takes a pig to roll a distance of 6 m at a speed of 8 m/s? 0.7 m/s

Rudik [331]

Answer:

0.75 s

Explanation:

From the basic definition of sleed as distance traveled per unit time, s=d/t and making t the subject of the formula then t=d/s where t is time of traveling, d is distance covered and s is the speed. Substituting 6m for distance, d and 8 m/s for speed s then the time is calculated as t=6/8=0.75 s

Therefore, time is equivalent to 0.75 s

A 120-meter-long ski ift carries skiers from a station at the foot of a slope to a second station 40 m above. what is the IMA (i

Pepsi [2]

The ideal mechanical advantage (IMA) of an inclined plane is given by:
$IMA = \frac{L}{h}$
where L is the length of the inclined plane while h is the height.
In our problem, L=120 m and h=40 m. Therefore, the IMA of the ski lift is
$IMA= \frac{120 m}{40 m}=3$

Predict the gravitational force between two 15-kg balls whose centers are 35 m apart.

ArbitrLikvidat [17]

$F=G\frac{m_1-m_2}{r^2}$

$=\frac{(6.67\times10^{-11}N*m/kg^2)(15kg) }{(0.35m)^2}$

$=1.2\times10^{-7} N$

Because the weight of one ball is mg = 147 N, the gravitational force between the two balls is $1.2\times10^{-7}N$ or $8.4*10^3$ parts per billion of the weight.
