Raindrops are falling straight down at 12 m/s when suddenly the wind starts blowing horizontally at a brisk 4.0 m/s. From your point of view, the rain is now coming down at an angle. What is the angle? Express your answer using two significant figures.
tan theta = Y/x
tan theta = 12/4 = 3
theta = 72.16 deg
angle with horizontal = 90-72 = 18 deg

5. Rain is falling vertically with a speed of 30 ms. Suddenly wind starts blowing from north to south with a speed of 10 ms. In which direction should a person waiting at a bus stop hold his umbrella.
A soccer player is running at 4.7 m/s when it begins to rain. The raindrops are falling straight down at 3.1 m/s, What is the speed and direction of the raindrop as it hits the soccer players face?
Review PartA While driving north at 25 m/s during a rainstorm you notice that the rain makes an angle of 38 with the vertical. While driving back home moments later at the same speed but in the opposite direction, you see that the rain is falling straight down From these observations, determine the speed of the raindrops relative to the ground Express your answer with the appropriate units. alue Units Submit Request Answer PartB From these observations, determine the angle...
A skier is gliding along at 3.0 m/s on horizontal, frictionless snow. He suddenly starts down a 10∘ incline. His speed at the bottom is 11 m/s . A) What is the length of the incline? Express your answer with the appropriate units. B)How long does it take him to reach the bottom? Express your answer with the appropriate units.

Express your answer to two significant figures and include the appropriate units. b)What is the direction of the impulse that the bat delivers to the ball? Express...
Your car tire is rotating at 3.8 rev/s when suddenly you press down hard on the accelerator. After traveling 260 m the tire's rotation has increased to 5.6 rev/s. The radius of the tire is 32 cm. What was the tire's angular acceleration? Give your answer in rad/s Express your answer using two significant figures rad/s2
Your car tire is rotating at 3.4 rev/s when suddenly you press
down hard on the accelerator. After traveling 240 m, the tire's
rotation has increased to 6.6 rev/s. The radius of the tire is 32
cm.
What was the tire's angular acceleration? Give your answer in
rad/s^2.
Express the answer using two significant digits.
The answer I got is, approximately, 0.013405, but, apparently,
it's wrong.

A 0.145-kg baseball pitched horizontally at 36.7 m/s strikes a bat and is popped straight up to a height of 52.5 m . Part B Calculate the direction of the average force on the ball during the contact. Express your answer using two significant figures. Part A If the contact time is 3.00 ms , calculate the magnitude of the average force on the ball during the contact. Express your answer using two significant figures.
A sky diver jumps from a helicopter and is falling straight down at 30 m/s when her parachute opens. From then on, her downward acceleration is approximately = g - cv^2, where g = 9.81 m/s^2 and c is a constant. After an initial "transient" period the descends at a nearly constant velocity of 5 m/s. (a) What is the value of c, and what are its 9 units? (b) What maximum deceleration is the sky diver subjected to? (c)...
