A bird, accelerating from rest at a constant rate,

Physics
1 answer:
creativ13 [48]3 years ago
3 0

Answer:

the speed of the bird is 2.8 m/s in after 11 seconds.

Explanation:

given,

displacement of bird = 28 m

time taken of the displacement of 28 m = 11 s

distance = speed × time                      

velocity = \dfrac{displacement}{time}

             =\dfrac{28}{10}  

             = 2.8 m/s                                                  

hence, the speed of the bird is 2.8 m/s in after 11 seconds.

aniked [119]

Answer:

The woman's distance from the right end is 1.6m = (8-6.4)m.

The principles of moments about a point or axis running through a point and summation of forces have been used to calculate the required variable.

Principle of moments: the sun of clockwise moments must be equal to the sun of anticlockwise moments.

Also the sun of upward forces must be equal to the sun of downward forces.

Theses are the conditions for static equilibrium.

Explanation:

The step by step solution can be found in the attachment below.

Thank you for reading this solution and I hope it is helpful to you.

What is the velocity (in m/s) of a 550 kg roller coaster cart at the bottom of the track if it started with 990,000 J of gravita
sesenic [268]

Answer:

60m/s

Explanation:

initial energy = final energy

g.p.e = k.e

k.e = 0.5 × mass × velocity²

g.p.e = 990000J as per Question

990000Nm = 0.5 × 550 × V²

V² = 3600

V = 60m/s

BigorU [14]

Answer:

inertia

Explanation:

The property of matter that will keep the body in motion when the car comes to a halt is the inertia force.

Inertia is the ability of a body to remain in static position. It is the tendency to remain in a stable condition where there is no motion.

  • Newton's first law is the law of inertia and it states that a body remain in a state of rest or of uniform motion unless acted upon by an external force.
  • The ability to remain in state of rest by a body is predicated on the force of inertia.
