In a supermarket, a person pushes his 16-kg shopping cart with a force of magnitude 56 N and a direction of 30° below the horizontal. When passing through the candy aisle, he decides not to stop i because he is on a diet, so he travels a distance of 10 m at a speed that we can consider constant. What work did the friction do as the person passed through the candy aisle? a) W = -484.9742 J. b) W = -560 J. %3D T77

A hummingbird hovers by exerting a downward force on the air equal, on average, to its weight. By Newtons third law, the air exerts an upward force of the same magnitude on the birds wings. Find the average mechanical power delivered by a 3.00-g hummingbird while hovering if its wings beat 80.0 times per second through a stroke 3.50 cm long.

(b) Suppose instead the car hits a concrete abutment at full speed and is brought to a stop in 2.00 m. Calculate the force exerted on the car and compare it with the force found in part (a).

The system shown in Figure P5.43 is used to lift an object of mass m = 76.0 kg.

At the bottom of an air track tilted at angle , a glider of mass m is given a push to make it coast a distance d up the slope as it slows clown and stops. Then the glider comes back down the track to its starting point. Now the experiment is repeated with the same original speed but with a second identical glider set on top of the first. The airflow from the track is strong enough to support the stacked pair of gliders so that the combination moves over the track with negligible friction. Static friction holds the second glider stationary relative to the first glider throughout the motion. The coefficient of static friction between the two gliders is ,. What is the change in mechanical energy of the two-gliderEarth system in the up- and down-slope motion after the pair of gliders is released? Choose one.
