The eastern time zone would the opposite side of the angle made by his car. So this means he would be traveling 30cos30 m/s completely in the east direction. Or approximately 26 m/s in the East direction. 5000 m divided by this answer results in approximately 192 seconds. I would use a calculator to get a more exact answer

Answer:
E₂ / E₁ = 521.64 / 5.95 =87.67
Explanation:
Let d be the distance covered inside electric field . Lt q be the magnitude of charge.
Force under field E₁ = q E₁
acceleration = qE₁/ m
d = 1/2 a t²
d = .5 ( qE₁ / m) x 32.3²
d = 521.64 ( qE₁ / m)
Similarly for return journey,
d = .5 x ( qE₂ / m) x 3.45²
d = 5.95x( qE₂ / m)
521.64 ( qE₁ / m) = 5.95x( qE₂ / m)
E₂ / E₁ = 521.64 / 5.95 =87.67
Answer: 90000 kgm/s
Explanation:
Given that,
Momentum of car = ?
Mass of car = 1,5000 kg
Velocity of car = 6 m/s
Recall that momentum is the product of mass of the moving object by its velocity
i.e Momentum = mass x velocity
Momentum = 15000kg x 6m/s
= 90000kgm/s
Thus, the momentum of the car is 90000 kgm/s
