Q. As you ride your 14-kg bicycle on level ground you do some work against a 30N force of air resistance if your mass is 65-kg.What is power you apply to maintain a velocity of 25-km`.a-on level ground b-going up a 5degrees slope?(remember it's a numerical please solve this)
Q. A 41 kg box is being pushed a distance of 7m across the floor by a force P whose magnitude is 151-N. The force P is parallel to the displacement of the box. The coefficient of kinetic friction is 0.25. Determine the work completed on the box by each of the four forces that act on the box. Be sure to include proper plus or minus sign for the work completed by each force.
What is a stopping distance
Blocks with masses of 2 , 4 , and 6 are lined up in a row on the frictionless table. All three are pushed forward by a 56 force applied to the 2 block. How much force does the 4 block exert on the 6 block.
What are the magnitude and direction of the net force. how long does it take for the police car to catch up with the speeder.
How fast should a car move toward you for the car's horn to sound 2.88% higher in frequency than as the car is stationary? The speed of sound is 343 m/s.
Heather and Jerry are standing on a bridge 45m above a river. Heather throws a rock straight down with a speed of 19m/s. Jerry, at exactly the same instant of time, throws a rock straight up with the same speed. Overlook air resistance. How much t..
find the maximum distance she can be from the craft and still return within 2.30 min (the amount of time the air in her helmet remains breathable).
Write the formula of the root-mean-square deviation (RMSD) between two molecular structures - Computational Biophysics and Nanoscale Simulations
suppose that both cars start at the same point, how much sooner does the faster car arrive at a destination 35 km away.
Find out the magnetic field strength
Assume a small child rolls off a bed that is 0.38m above the floor. If the floor is hardwood, the child's head is brought to rest in approximately 2.2mm. If the floor is carpeted, this stopping distance is increased to about 1.1cm.
