A woodchuck runs 22 m to the right in 9 s, then turns and runs 11 m to the left in 4 s. (Assume motion to the right is positive. Where applicable, indicate the direction with the sign of your answer. Enter your answers in m/s.) (a) What is the average velocity of the woodchuck? m/s (b) What is its average speed? m/s

A ball is thrown straight down at 1.29 m/s and hits the ground 1.07 seconds later. How many meters did the ball travel before hitting the ground? Type your answer.

Compute your  Average velocity in the following two cases: (a)  You walk 61.4 m at a speed of 2.47 m/s and then run 61.4 m at a speed of 3.34 m/s along a straight track. (B)  You walk for 1 minute at a speed of 2.47 m/s and then run for 1.8 minutes at 3.34 m/s along a straight track

A gnat takes off from one end of a pencil and flies around erratically for 3 s, seats on a wall for 2.4 s,  and continues flying for the next 1.1 seconds before landing on the other end of the same pencil.  If the gnat flew a total distance of 2.6 m, and the pencil is 9 cm long, find the magnitude of the gnat's average velocity.           Answer units

What is the total time it takes for a ball that is tossed straight up at 10 m/s to reach the top of its path and then return to its starting point? Hint: since the ball returns to its starting point, what is its displacement? Your answer should be in units of seconds but you should only submit the number for your answer

The vertical displacement (in m) of a plane is  1.5 t2 up; t is the time (in s) after takeoff. The plane releases a package 2.0 s after takeoff. What is the magnitude of the velocity (in m/s) when the packaged is released? Report your answer in the appropriate number of significant digits. Answer value

Chapter 02, Problem 10 In reaching her destination, a backpacker walks with an average velocity of 1.26 m/s, due west. This average velocity results, because she hikes for 6.62 km with an average velocity of 2.54 m/s due west, turns around, and hikes with an average velocity of 0.381 m/s due east. How far east did she walk (in kilometers)? dw VE West East dɛ Number Units the tolerance is +/-2% Click if you would like to Show Work for this question: Open Show Work

5. A cyclist rides 8.0 km east for 20 minutes, then he turns and heads west for 8 minutes and 3.2 km. Finally, he rides east for 16 km, which takes 40 minutes. (a) What is the final displacement of the cyclist? (b) What is his average velocity?

A hot air balloon is moving vertically upwards at a constant rate of 9.0 m/s. As the balloon rises, a package is dropped from the balloon and it takes 5 s to hit the ground. How far did the package fall?   Make sure to include a diagram of the physical situation, label know and unknown quantities with units, coordinate system. Please use grade 12 kinematics and label the variables as v1, v2, a (Acceleration), t (time), d (displacement) Thanks!

A particle moves so that its position (in meters) as a function of time (in seconds) is r = î + 2t² j+ 2tk. (Use the following as necessary: t.) (a) Write an expression for its velocity as a function of time. v(t) = m/s (b) Write an expression for its acceleration as a function of time. d(t) = m/s2 Submit Answer
