IP A jogger runs with a speed of 3.10 m/s in a direction 25.0 ∘ above the x axis. Explain your steps. a) Find the x and y components of the jogger's velocity in m/s. b) How will the velocity components found in part (a) change if the jogger's speed is halved? Answer in m/s.
A jogger runs at 9 m/s and is trailed by a bumblebee moving at 5 m/s and buzzing at a frequency of 270 Hz. What frequency does the jogger hear if the speed of sound in the air is 336 m/s?
a) A 75.2-kg jogger runs with a velocity of 2.85 m/s. How much kinetic energy does the jogger have? b) During a football game, a 70-kg running back runs with a speed of 5.15 m/s while a 120-kg lineman runs with a speed of 2.20 m/s. Which player has the greater inertia? Why?
Jogger A has a mass m and a speed v, jogger B has a mass m/2 and a speed 3v, jogger C has a mass 3m and a speed v/2, and jogger D has a mass 4m and a speed v/2. Rank the joggers in order of decreasing kinetic energy. Indicate ties where appropriate.
A jogger runs around a circular track of 30 m radius, as shown
in the figure. She runs at constant speed in a clockwise direction
for a few minutes. She completes a round in 40 s.
Using N, S, E, W, cw, or ccw for the direction, compare the
directions and magnitudes of her linear velocity, linear
acceleration, angular velocity and angular acceleration at A, B and
C
An 60-kg jogger is heading due east at a speed of 3.3 m/s. A 80-kg jogger is heading 68 ° north of east at a speed of 2.8 m/s. Find (a) the magnitude and (b) the direction of the sum of the momenta of the two joggers. Describe the direction as an angle with respect to due east.
An 85-kg jogger is heading due east at a speed of 2.3 m/s. A 55-kg jogger is heading 22° north of east at a speed of 3.7 m/s. Find the magnitude and direction of the sum of momenta of the two joggers. magnitude kg · m/s direction °
An 85-kg jogger is heading due east at a speed of 2.4 m/s. A 55-kg jogger is heading 22° north of east at a speed of 3.1 m/s. Find the magnitude and direction of the sum of momenta of the two joggers. magnitude kg · m/s direction °
