What is the force on the ball of mass 0.2 kg moves with a velocity of 20 m sec and it stops in 0.1 sec?

What is the force on the ball of mass 0.2 kg moves with a velocity of 20 m sec and it stops in 0.1 sec?

F=0.2×200.1=40N. Was this answer helpful? A ball of mass m=0.2 kg is moving with velocity vi=60 m/s and a force acts on the ball for a instant and changed its velocity to vf=90 m/s in same direction.

What does a ball of mass 4kg moving on a smooth horizontal surface make?

A ball of mass 4 kg moving on a smooth horizontal surface makes an elastic collision with another ball of mass m at rest in the line of motion of the first ball. If after collision first ball moves in the same direction with one fourth of its velocity before collision, then the mass of second ball is: (1) 4 kg.

What will be the wave length of a ball of mass 0.2 kg moving with a velocity of 10m s?

λ=hmv=(6.6×10−34)0.2×1.4×10−3=2.35×10−30m.

What is the force of gravity on the ball when a 1kg ball is dropped on earth?

w=mg=(1.00kg)(9.80m/s2)=9.80N. w = m g = ( 1.00 kg ) ( 9.80 m/s 2 ) = 9.80 N . When the net external force on an object is its weight, we say that it is in free fall, that is, the only force acting on the object is gravity.

What is the force required to move a mass of 1kg at rest on a horizontal?

• Step 1 : Given data. Mass. Coefficient of friction. μ = 0 . Acceleration due to gravity. g = 9 . 8 m s – 2. N = Normal force. Step 2 : To find the force. Force , …
• Step 2 : To find the force. Force , F = f r = μ N = μ m g F = 0 . 1 × 1 × 9 . 8 = 0 . 98 N. Hence the force is. 98 N. Therefore the correct answer is Option A.

When a particle of mass 2 kg moves on a smooth horizontal plane?

A particle of mass 2kg moves on a smooth horizontal plane under the action of a single force→F=(3^i+^j)N. Under this force it is displaced from (0,0) to (1m,1m). The initial speed of the particle is √3m/s and final speed is √5km/s.

What is a ball of mass 2kg is dropped from a high building?

Expert-Verified Answer answer is 384 joules {Ans.}

What is the formula for a moving wave?

The wave moves with a constant velocity vw , where the particles of the medium oscillate about an equilibrium position. The constant velocity of a wave can be found by v=λT=ωk. v = λ T = ω k .

What is the formula of change in momentum?

Step 1: Identify the mass of the object, , the initial velocity of the object, , and the final velocity of the object, . Step 2: Calculate the change in momentum, which is equal to the impulse, , using the formula Δ p = m ( v f − v i ) .

What will be the wavelength of a ball of mass is 0.1 kg moving with a velocity of 10 Metre per second?

Final answer : wavelength of the ball (λ)=6.626×10−34m.

What if 0.2 kg ball is thrown with a velocity of 6?

The formula for kinetic energy is: KE = (1/2)mv^2 Now, we can plug in the values for mass and velocity: KE = (1/2)(0.2 kg)(6 m/s)^2 KE = (1/2)(0.2 kg)(36 m^2/s^2) KE = (0.1 kg)(36 m^2/s^2) KE = 3.6 kg m^2/s^2 So, the kinetic energy of the ball is $\boxed{3.6 \text{ J}}$ (Joules).

What is the net force acting on a 1.0 kg ball moving at a constant velocity?

Since the body is moving with a uniform velocity which is not changing,due to Newton’s first law,net force acting on it is zero. Was this answer helpful?

What is the net force acting on an object of mass 10 kg moving with a constant speed of 10 m per second?

⇒F=m(v−u)t=10(−2−10)4=−30 N.

What is the net force acting on a body of mass 10 kg moving with a uniform?

As we know, F=mass of body×acceleration of body by Newton’s second law of motion. Therefore, force is zero.
