For a movie scene, a 75kg stuntman drops from a tree onto a 55kg sled that is moving on a frozen lake with a velocity of 15m/s toward the shore
Part A What is the speed of the sled after the stuntman is on board?
Part B If the sled hits the bank and stops, but the stuntman keeps on going, with what speed does he leave the sled? (Neglect friction.)
A 1300- {rm N} crate slides 15- {rm m} down a ramp that makes an angle of 35^circ with the horizontal. If the crate slides at the constant speed, how much thermal energy is created.
River Pascal with a volume flow rate of 3.3×10^5 joins with River Archimedes, that carries 1.09×106 , to form the Bernoulli River. The Bernoulli River is 120 wide and 20 deep.
What current is in the primary circuit. A proton moves at a speed of 8.0 103 m/s as it passes through a magnetic field of 0.55 T. Find the radius of the circular path. Note down that the charge carried by the proton is equal to that of the electron..
A bus is traveling up a hill at a speed of 34m/s. The hill is 23 degrees relative to horizontal and the coefficient of static friction between the bus's tires and the road is 0.6
A diver 40 m deep in 10 degree Celcius fresh water exhales a 0.50-cm-diameter bubble. What is the bubble's diameter just as it reaches the surface of the lake, where the water temperature is 20 degrees Celcius? Assume that the air bubble is always in..
A virtual image is formed 22.0cm from a concave mirror having a radius of curvature of 44.0cm. find the position of the object
A 5.0 nC point charge sits at x = 0. At the same time, a 4300 N/C uniform electric field (created by distant source charges) points in the positive x-direction. A. At what point along the x-axis, if any, would a proton experience no net force? B. ..
After the engine is ignited, what is the rocket's speed when the spring has stretched 19.00 cm past its natural length? What would be the rockets speed after travelling the distance if it weren't tied down to spring.
If the combination with this amount of turpentine is after that cooled back to 19°C, how far below cylinder's rim does the turpentine's surface recede.
A dead tree is initially stationary and there is a 30.0-degree angle between the tree and the vertical. The roots finally give way and the tree topples to the ground (rotating on an axis that is parallel to the level ground and intersecting the ba..
Archimedes purportedly used his principle to verify that the king's crown was pure gold by weighing the crown while it was submerged in water.
A meter stick supported at the 50 cm mark has masses of 300 g & 200 g hanging from it at the 10-cm & 60-cm mark, respectively. Where should we hang a third, 400-g mass to keep the meter stick balanced?
