Answer:
Velocity of skater after throwing the snowball is 2.57 m/s
Explanation:
Given :
Mass of skater, M = 62.2 kg
Mass of snowball, m = 0.145 kg
Velocity of snowball relative to ground, v = 39.3 m/s
Consider v₁ be the velocity of skater after throwing the snowball.
According to the problem, initially the velocity of skater and snowball is same. So,
Velocity of skater before throwing snowball, u = 2.66 m/s
Applying conservation of momentum,
Momentum before throwing snowball = Momentum after throwing snowball
(M + m) u = Mv₁ + mv
Substitute the suitable values in the above equation.
v₁ = 2.57 m/s
B is the answer to this problem
Answer:
The moon Phobos orbits Mars (m = 6.42 x 1023 kg) at a distance of 9.38 x 106 m.
Answer:
\frac{R}{^{\sqrt{2}}}
Explanation:
q1 = q , q2 = q
m1 = M, m2 = 2M
Potential difference is V
Let v1 be the speed of first particle and v2 be the speed of second particle.
Energy due to potential difference gives the kinetic energy to the particle.
1/2 m x v^2 = e V
v^2 = 2 e V / m = 2e V / m ... (1)
Now radius is given by
r = m v / B q
by eqution (1)
For first particle
.... (2)
For second particle
.... (3)
Divide equation (2) by equation (3), we get
So
r1 / r2 =
