What is the velocity of a ball dropped from a height of 150 m when it hits the ground? Take the upward direction as positive.

Answer:

The velocity of the ball when its hit the ground will be 54.22 m/sec    

Explanation:

We have given height from which ball is dropped h = 150 m

Acceleration due to gravity g=9.8m/sec^2

As the ball is dropped so initial velocity will be zero so u = 0 m/sec

According to third equation of motion we know that v^2=u^2+2gh

v^2=0^2+2\times 9.8\times 150

v=54.22m/sec

So the velocity of the ball when its hit the ground will be 54.22 m/sec

A circular wire loop of radius 15.0 cm carries a current of 2.60
Korolek [52]
Part (a): Magnetic dipole moment

Magnetic dipole moment = IA, I = Current, A = Area of the loop
Then,
Magnetic dipole moment = 2.6*π*0.15^2 = 0.184 Am^2

Part (b): Torque acting on the loop
T = IAB SinФ, where B = Magnetic field, Ф = Angle
Then,
T = Magnetic dipole moment*B*SinФ = 0.184*12*Sin 41 = 1.447 Nm

As you take your leisurely tour through the solar system, you come across a 1.45 kg rock that was ejected from a collision of as
nikklg [1K]

Answer:

1.3310\times 10^8 m/s is the rock's speed.

Explanation:

Momentum is defined as motion possessed by the moving body's mass. Mathematically it a product of mas and velocity of the body.

Momentum(P)=Mass(m)\times velocity(v)

Given : Mass of rock = m = 1.45 kg

Velocity of the rock = v

Momentum of the rock = P =1.93\times 10^8 kg m/s

1.93\times 10^8 kg m/s=1.45 kg\times v

v=\frac{1.93\times 10^8 kg m/s}{1.45 kg}=1.33\times 10^8 m/s

1.3310\times 10^8 m/s is the rock's speed.
