What is the mass of a student that weighs 3000N stands on one foot, balancing on a step stool.
Mkey [24]

Weight = (mass) x (gravity)

so

Mass = (weight) / (gravity)

Mass = (3000N) / (9.8 m/s^2)

Mass = 306.1 kg

But he could never stand on one foot balanced on a step stool. The poor kid weighs 675 pounds ! !

A net force of 20 N acting on a wooden block produces an
Ymorist [56]

Answer:

From the second law of motion:

F = ma

we are given that the force applied on the block is 20N and the block accelerates at an acceleration of 4 m/s/s

So, F=  20N   and  a = 4 m/s/s

Replacing the variables in the equation:

20 = 4* m

m = 20 / 4

m = 5 kg

The position function of a particle is given by s=2t3−3t2−63t,t⩾0.s=2t3−3t2−63t,t⩾0. where ss is measured in meters and tt in se
Kisachek [45]

Answer:

t=5.72\ s

Explanation:

Given:

the displacement as the function of time:

s=2t^3-3t^2-63t

here time is in seconds and the displacement in meters.

Now we differentiate this eq. of displacement to get the equation of velocity:

v=\frac{d}{dt}(s) \\v=6t^2-6t-63

According to given the velocity is 99\ m.s^{-1} at some time:

99=6t^2-6t-63

6t^2-6t-162=0

t=5.72\ s &  is the only time  for (t>=0) instances when the particle will have a velocity of 99\ m.s^{-1} but in the opposite direction.
