What is the angular position in radians of the minute hand of a clock at 7:00?
A clock has a minute hand that is 12cm long. a. What is the angular speed of the minute hand? Give your answer in radians per second. Give an exact answer. (Hint: how long does the minute hand take to make a complete rotation?) b. What is the linear speed of the tip of the minute hand? Give an exact answer in cm per second.
At 3:00 the hour hand and the minute hand of a clock point indirections that are 90.0 degrees apart. What is the firsttime after 3:00 that the angle between the two hands has decreasedby half to 45.0 degrees?
Half Time At 3:00 the hour hand and the minute hand of a clock point in directions that are 90.0 ∘ apart. What is the first time after 3:00 that the angle between the two hands has decreased by half to 45.0 ∘ ?
Through how many radians will the hour hand on a clock rotate in (a) 13 hr? In (b) 5 hr? (a) In 13 hr, the hour hand on the clock will rotate radians. (Type an exact answer in terms of a. Type an integer or a simplified fraction.) (b) In 5 hr, the hour hand on the clock will rotate radians. (Type an exact answer in terms of . Type an integer or a simplified fraction.)
Through how many radians will the hour hand on a clock rotate in (a) 18 hr? In (b) 4 hr? (a) In 18 hr, the hour hand on the clock will rotate radians. (Type an exact answer in terms of 1. Type an integer or a simplified fraction.) (b) In 4 hr, the hour hand on the clock will rotate radians. (Type an exact answer in terms of t. Type an integer or a simplified fraction.)
Find the angular velocity in radians per minute and linear velocity in inches per minute for a point on the edge of a 6.1-in.-diameter record spinning at 42 rev/min The angular velocity is radians per minute. (Simplify your answer. Type an integer or decimal rounded to the nearest tenth.) The linear velocity is inches per minute (Simplify your answer. Type an integer or decimal rounded to the nearest tenth.)
The minute hand of a church clock is twice as long as the hour hand. After what time after midnight does the end of minute hand move away from the end of the hour hand at the fastest rate A) 11 minutes past midnight C) 32 minutes past midnight B) 21 minutes past midnight D) 47 minutes past midnight
A pendulum clock is calibrated so that the minute hand goes once around the clock-face whenever the pendulum swings a certain number of times (in exactly an hour). If that same clock is taken up to the Moon, where the acceleration due to gravity is 1.63 m/s ^2 , find the time it will take for the minute hand to make a full revolution on the clock face.
MATLAB code help! Function Name: chemTimer Inputs: 1. (double) The current position of the hour hand 2. (double) The current position of the minute hand 3. (double) A positive or negative number of minutes Outputs: 1. (double) The position of the hour hand after the specified time 2. (double) The position of the minute hand after the specified time Background: Oh no, you were running late to your Chem lab and completely forgot your reaction timer! It's a good thing...
Question 1 1 pts What is the angular speed in radians per second (rad/s) of the hour hand on an analog clock? A 1.5 x 1o4 rad/s B. 1.7 x 103 rad/s C 0.20 rad/s D. 0.052 rad/s O D Question 2 1 pts A record player rotates a record at 45 revolutions per minute. When the record player is switched off, it makes 4.0 complete turns at a constant angular acceleration before coming to rest. What was the magnitude...
