A particle moves at a constant speed of 34 m/s in a circular path of radius 6.3 m. From this information, what can be calculated
Yakvenalex [24]

Answer:

Centripetal acceleration

Explanation:

  • The centripetal acceleration is the motion inwards towards the center of a circular path.
  • <em><u>Centripetal acceleration is given by; the square of the velocity, divided by the radius of the circular path. </u></em>
  • That is;

         ac = v²/r

         Where; ac = acceleration, centripetal, m/s², v is the velocity, m/s and r is the  radius, m

What does the slope of a velocity-time graph reveal about an objects motion
Ivan

Answer:

The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.

A satellite at a particular point along an elliptical orbit has a gravitational potential energy of 4700 MJ with respect to Eart
erastovalidia [21]

during satellite motion we know that total energy is always conserved

so here we will have

KE_i + PE_i = KE_f + PE_f

here we know that

KE_i = 4800 MJ

PE_i = 4700 MJ

now at other position

PE_f = 6000 MJ

now from above equation we have

4800 +4700 = 6000 + KE

now we have

9500 = 6000 + KE

KE = 9500 - 6000 = 3500 MJ

so its kinetic energy will be 3500 MJ

During a test crash and airbag in place to stop at dummies forward motion the dummies mass is 75 kg if the net force of the dumm
strojnjashka [21]
The dummy's acceleration is 11 m/s^2
(also known as 11 meters per sec. per sec.)

a = F/m
   = 825 N/75 kg
   = 11 m/s^2

A beaker contains 450g of water at a temperature of 24C, The therman capacity of the beaker is negligible and no heat is gained
valentina_108 [34]
Given:

450 grams of water (Tw = 24 C) 
Thermal capacity of the beaker = negligible
Q = 0 
Tice = 0 C
Tfinal = 8 C

450g * (Tf - Tw) + m_ice * (Tice - Tw) = 0

450g * (8 - 24) + m_ice (0 - 24) = 0 

solve for m_ice
