A duck is projected horizontally with a velocity of 45 m/s from a height of 180 m. Find its horizontal velocity as it hits the ground.
What is 45 m/s?
The change of motion of an object is proportional to the force impressed; and is made in the direction of the straight line in which the force is impressed.
Newton's 2nd Law of Motion
What is 5.700 x 10^14?
The resultant speed if an airplane flying due north at 80 km/h relative to the surrounding air is caught in a 60-km/h crosswind (wind blowing at a right angle to the direction of the airplane) that blows it off its intended course.
What is 100 km/h?
A Shuumi accelerates from rest to 20m/s in 4 seconds. Assume uniform acceleration, find her average acceleration and displacement in this time.
