A second baseman tosses the ball to the first baseman, who catches it at the same level from which it was thrown. The throw is made with an initial speed of 21.0 m/s at an angle of 39.0° above the horizontal. (Neglect air resistance.)
(a) What is the horizontal component of the ball's velocity just before it is caught? m/s
(b) How long is the ball in the air?
The resolution of the eye is ultimately limited by pupil diameter. What is the smallest diameter spot an eye can produce on the retina if pupil diameter is 4.45? Assume light with a wavelength of = 600 .
The wind blows with a force of 425N north on a sail boat, while the water exerts a force of 325N west on the sailboat. Find out the magnitude and direction of the net external force on the sailboat.
What should be the spring constant of a spring designed to bring a 1500 car to rest from a speed of 80 so that the occupants undergo a maximum acceleration of 5.
The rock reaches a maximum height of 2×10^3 m, above the surface of the planet, before it falls back down. What was the first speed of the rock as it left the astronaut's hand.
