Answer:
When the y-coordinate is 12m, the x-coordinate of the particle is 24 m
Explanation:
Given;
y - component of acceleration = 1 m/s²
X - component of acceleration = 2 m/s²
distance traveled in y - direction, Dy = 12 m
To determine the distance traveled in X- direction, we obtain the duration of the displacement in y- direction.
Applying equation of motion;
Dy = ¹/₂ x at²
For distance traveled in x -direction;
Dx = ¹/₂ x at²
Dx = ¹/₂ x 2 x (4.9)² = 24.01 m ≅ 24m
Therefore, when the y-coordinate is 12m, the x-coordinate of the particle is 24 m
Answer:
454 km
Explanation:
A train travels at 227 km per hour ( at average). So to find the distance it travels for 2 hours, you simply multiply the avg speed by time travelled.
James watt compared staem engine power to the power of a horse. in 1 s, horse lifted 75kg 1 m. therefore, hp= 735.5 watts
