Answer:

Explanation:

If no one can see it because the lights were out. Did the flea really jump?

What do you want here?

Max height (2.2sin21)²/ 2(9.8) = 3.2 cm

Time of flight 2(2.2sin21)/ (9.8) = 0.16 s

distance of flight (2.2cos21)(0.16) = 33 cm

A car is stopped for a traffic signal. When the light turns green, the car accelerates, increasing its speed from 0 to 5.10 m/s
yarga [219]

Answer:

I=336.6kgm/s

Explanation:

The equation for the linear impulse is as follows:

I=F\Delta t

where I is impulse, F is the force, and \Delta t is the change in time.

The force, according to Newton's second law:

F=ma

and since a=\frac{v_{f}-v_{i}}{\Delta t}

the force will be:

F=m(\frac{v_{f}-v_{i}}{\Delta t})

replacing in the equation for impulse:

I=m(\frac{v_{f}-v_{i}}{\Delta t})(\Delta t)

we see that \Delta t is canceled, so

I=m(v_{f}-v_{i})

And according to the problem v_{i}=0m/s, v_{f}=5.10m/s and the mass of the passenger is m=66kg. Thus:

I=(66kg)(5.10m/s-0m/s)

I=(66kg)(5.10m/s)

I=336.6kgm/s

the magnitude of the linear impulse experienced the passenger is 336.6kgm/s

zysi [14]

Answer:

16 % and 9 %

Explanation:

Accurate reading = 10 N

reading of first balance = 8.4 N

reading of second balance = 9.1 N

Percentage difference in first reading

= \frac{True reading - reading of first balance}{True reading}\times 100 %

= \frac{10-8.4}{10}\times 100 % = 16 %

Percentage difference in second reading

= \frac{True reading - reading of second balance}{True reading}\times 100 %

= \frac{10-9.1}{10}\times 100 % = 9 %
