Answer:
34.35464 m/s
Explanation:
q = Charge of electron =
E = Electric field = 0.08 N/C
s = Displacement =
m = Mass of electron =
Electrical force is given by
Work done is given by
Work done is also given by the kinetic energy
The velocity of the electron is 34.35464 m/s
Answer:
-19 is the answer because put the value of x=13 then make equation
Explanation:
One of the interesting things about projectile motion is that the horizontal motion is independent of the vertical motion. Recall that in freefall, an object continually experiences a downward acceleration of 9.80ms2 but has no horizontal acceleration.
Answer:
101 J
Explanation:
The kinetic energy of an object is given by
where
m is the mass of the object
v is its speed
For the baseball in this problem,
m = 0.140 kg
v = 38.0 m/s
Substituting into the equation, we find the kinetic energy of the ball:
