- What distance d, in meters, does the plate move in 1.9 seconds at this speed? d = ______mA girl is riding her bicycle due north in a straight line at speed of 13.8 m/s and slows down to a speed of 9.2 m/s in 7s what is the magnitude of the girls acceleration ?? Round to 1 decimal placeA boxer's fist and glove have a mass of m = 1.04 kg. The boxer's fist can obtain a speed of v = 9.25 m/s in a time of t = 0.21 s. Write a symbolic expression for the magnitude of the average acceleration, aave, of the boxer's fist, in terms of the variables provided. Find the magnitude of the average acceleration, aave, in meters per square second. Write an expression for the magnitude of the average net force, Fb, that the boxer must apply to his fist to achieve the given velocity. (Write the expression in terms of m, v and t.) What is the numerical value of Fb, in newtons?
- For each of five trials, find the acceleration from ax= (twice distance glider moves)/(time squared) The glider & hanging mass have the same acceleration, and we will call to the left the +x direction for the glider, and down the +x direction for the hanging mass. Using Microsoft Excel, plot a graph of the acceleration vs. the size of the hanging mass. Make sure the graph contains all of the features it should. This graph should have points that follow a straight line. Add a linear trendline to the graph and also display the equation for this line on the graph. We can show that Newton’s Laws predict that the acceleration should be ax=m2g/m1+m2 (3) where m1 is the glider’s mass and m2 is the amount of hanging mass. Equation (3) tells us that the predicted slope of your a x vs. m2 graph should be equal to g/(m1+ m2). Calculate the predicted value of the slope, and then find the percent error between it and the experimental value of the slope. When you do the % error calculation,…A 3 kg ball is thrown straight into the air at 8 m/s . How high does it travel?

One day, while visiting New York, you take your bathroom scale into the elevator and stand on it. The scale reads 150 lb as the door closes. The reading varies between 130 lb and 170 lb as the elevator makes its upward journey.In order to find the depth of the well you drop a stone into it and time its fall.
