Answer:

26.5 m/s at 2.17° east of north

Explanation:

The velocity component in the north direction:

vᵧ = 25.0 m/s + 1.75 m/s cos 35.0°

vᵧ = 26.4 m/s

The velocity component in the east direction:

vₓ = 1.75 m/s sin 35.0°

vₓ = 1.00 m/s

The magnitude of the velocity is:

v² = vₓ² + vᵧ²

v² = (1.00 m/s)² + (26.4 m/s)²

v = 26.5 m/s

The direction is:

θ = atan(vₓ / vᵧ)

θ = atan(1.00 m/s / 26.4 m/s)

θ = 2.17° east of north

A train travels 77 kilometers in 1 hour, and the 66 kilometers in 1 hour. What is the average speed?
Kipish [7]

Average speed = (total distance covered) / (time to cover the distance)

Total distance = (77km + 66km) = 143 kilometers

Time to cover the distance = 2 hours

Average speed = (143 km) / (2 hours) =  71.5 km per hour

What is the difference between free fall and weightlessness??
joja [24]
When you are in free fall, the force of gravity is stronger than your velocity perpendicular to where you're falling, and you move at a constant speed downwards.

Under feelings of weightlessness, you are still being pulled by gravity, but your perpendicular velocity and distance from the source can cancel each other out.

Which of the following concepts best explains why a mass of low-density material in the mantle rises?Multiple Choice Strain Buoy
SOVA2 [1]

Answer:

Bouyancy

Explanation:

Bouyancy occurs when the upthrust exerted on an object is equal to the weight of object displaced. It is mostly applicable to low density objects for example balloon. When balloon is displaced in water, it floats. This is due to the effect of the upthrust acting on the balloon which allows the balloon to float and which is opposite the weight.

Note that the weight acts downwards the object while the upthrust always acts opposite (upward)

How will the motion of the arrow change after it leaves the bow?
Pavel [41]

The string moves to the right, as it restores its original position with the median plane of the bow. As a result, the string "pulls" on the arrow with a force F2. 2. The tip of the arrow T moves slightly to the left.
