A 75?kg jogger runs with a speed of 4.2m/s.
Part A What is the jogger's de Broglie wavelength?
what is its kinetic energy at the end of the interval. How high a tree would a 80 kg person have to climb to increase his gravitational potential energy relative to the ground by that amount.
50 g ball travelling at 25.0 m/s is bounced off a brick wall and rebounds at 22.0m/s. A high-speed camera records this event. If the ball is in contact with the wall for 3.51 ms, what is the average acceleration of the ball throughout this time inter..
An airplane has an effective wing surface area of 15 m2 that is generating the lift force. What is the weight of the plane
A bicycle racer is traveling at 10 m/s with an acceleration of 0.5 m/s^2. The radius of the bicycle wheel is 33 cm. What is the angular velocity of the bicycle wheels
A descent vehicle landing on the moon has a vertical velocity toward the surface of the moon of 35.00m/s. At the equal time, it has the horizontal velocity of 55 m/s
Some amusement park rides move you back and forth in the horizontal direction. Why is this motion so much more disturbing to your body than cruising at a high speed in a jet airplane.
Now the gymnast (not holding any additional mass) walks directly above the right support. What is the force the left support exerts on the beam
A freight company uses a compressed spring to shoot 1.7 kg packages up a 1m high frictionless ramp into a truck. The spring constant is 241 N/m and the spring is compressed 33 cm.
