Is it possible to round a corner with a constant speed and a constant velocity

Physics
1 answer:
lianna [129]3 years ago
3 0

Explanation:

speed is just a measurement of relative movement, so you can round a corner with a constant speed. velocity is movement in a particular direction (it has a direction, vector),so you can't round a corner with a constant velocity

A 3.00-kg object has a velocity 16.00 i ^ 2 2.00 j ^2 m/s.
trapecia [35]

Answer:

390 J

Explanation:

m = 3 kg

u = 16 i + 2 j

(a) Magnitude of velocity = \sqrt{16^{2}+2^{2}} = 16.1245 m/s

KEi = 1/2 m v^2 = 0.5 x 3 x 16.1245 = 390 J

(b) v = 18 i + 14 j

Magnitude of velocity =  \sqrt{18^{2}+14^{2}} = 22.804 m/s

KEf = 1/2 m v^2 = 0.5 x 3 x 22.804 = 780 J

According to the work energy theorem

Work done = change in KE = KEf - KEi = 780 - 390 = 390 J

Assume that the mass has been moving along its circular path for some time. You start timing its motion with a stopwatch when it
lesya692 [45]

Answer:

v = R\omega(-sin\omega t \hat i + cos\omega t \hat j)

Explanation:

As we know that the mass is revolving with constant angular speed in the circle of radius R

So we will have

\theta = \omega t

now the position vector at a given time is

r = Rcos\theta \hat i + R sin\theta \hat j

now the linear velocity is given as

v = \frac{dr}{dt}

v = (-R sin\theta \hat i + R cos\theta \hat j)\frac{d\theta}{dt}

v = R\omega(-sin\omega t \hat i + cos\omega t \hat j)

Please help me with physics homework I just need help with C and D. Picture is included
marysya [2.9K]

Answer:

For C is B and for D is A

Explanation:

B because that's where the b car will do all the force to go up, and A because there the car doesn't have to do any force other than the natural, and it already brings that on it's own.

When a carpet is beaten with a stick dust comes out of it ...why
Mandarinka [93]

This can be explain through Newton’s first law of motion where an object at rest remain in rest unless acted upon by an unbalanced force. Hence, the dust particles having inertia and trapped within the pores of the carpet has the tendency to remain at the state of rest, it does not move and resist motion but when the carpet is beaten with a stick, dust comes out because the force from a stick acted upon it.
