An object of 4 kg has a speed of 6 m/s and moves a distance of 8 m. What is its kinetic energy in joules.

11Alexandr11 [23.1K]

Answer:

The answer to your question is Ke = 72 J

Explanation:

Kinetic energy depends on the speed of and object and its mass.

Data

mass = m = 4 kg

speed = v = 6 m/s

distance = d = 8 m

Kinetic energy = ke = ?

Formula

Ke = (1/2) mv²

Substitution

Ke = (1/2) (4)(6)²

Simplification

Ke = (1/2)(4)(36)

Ke = (1/2)(144)

Ke = 72 Joules

Result

Ke = 72 J

A proton travels at right angles through a magnetic field of 0.025 Tesla's. If the magnitude of the magnetic force on the proton

Varvara68 [4.7K]

Answer:

Velocity of proton will be equal to 4500 m/sec

Explanation:

We have given that proton moves right angles through a magnetic field

So angle between magnetic field and velocity of proton is $\Theta =90^{\circ}$

Magnetic field B = 0.025 Tesla

Charge on proton $e=1.6\times 10^{-16}C$

Magnetic force on the proton is given $F=1.8\times 10^{-14}N$

Magnetic force on a moving charge particle is equal to $F=qvBsin\Theta$

So $1.8\times 10^{-14}=1.6\times 10^{-16}\times v\times 0.025\times sin90^{\circ}$

v = 4500 m/sec

So velocity of proton will be equal to 4500 m/sec
