...for how long it takes in seconds? A car traveling 86 km/h is 140 m behind a truck traveling 71 km/h. Looking for how long it takes in seconds
Thanks big help
...videotapes a cheetah that is moving we? A cameraman on a pickup truck is traveling westward at 21 km/h while he videotapes a cheetah that is moving westward 30 km/h faster than the truck. Suddenly, the cheetah stops, turns, and then runs at 45 km/h eastward, as measured by a suddenly nervous...
a) What is the change in the Trucks Kinetic energy?
- I solved for this using 1/2m(Vf^2-Vi^2)
b) What is the magnitude of the change in the linear momentum of the truck.
- I know linear momentum is mass*velocity, yet I don't understand how solve this. I assume through the use of vectors.
c)...
the end, you are travelin? At the beginning of a 3.00 h plane trip, you are traveling due north at 192 km/h. At the end, you are traveling 240 km/h in the northwest direction (45.0° west of north).
#1)Find the change in your velocity.
Magnitude: km/h.
Direction (relativly to the east): °...
If the coefficient of friction between the road and the tires on a rainy day is 0.100, what is the minimum distance needed for the car to stop?
What is the stopping distance when the surface is dry and the coefficient of friction is 0.600?
flood victims isolated on a patch of lan? The pilot of an airplane traveling 180 km/h wants to drop supplies to flood victims isolated on a patch of land 125 m below. The supplies should be dropped how many seconds before the plane is directly overhead?
If a car is traveling at 45 km/h speeds up to 70 km/h in 8 seconds.....?
what would be the acceleration of the car in the units of meters per seconds squared?
i came up with .868 m/s/s after i converted the units. DONT FORGET TO CONVERT
...it hits a concrete wall.? Assume a 60 kg person was in the car that hit this wall. The velocity of the person equals that of the car both before and after the crash, and the velocity changes in 0.16 s.
(a) What is the average force exerted on the person?
(b) Some people think that they can...
speed of the motorist for...? A motorist travels 160 km at 40 km/h and 160 km at 100 km/h. What is the average speed of the motorist for this trip?
This is just an example of one of the review questions i found in my book. How would I answer this?
constant speed vertically with re? A car travels due east with a speed of 55.0 km/h. Raindrops are falling at a constant speed vertically with respect to the Earth. The traces of the rain on the side windows of the car make an angle of 75.0° with the vertical. Find the velocity of the rain with...
A boat leaves a dock at 7:00 P.M. and travels due south at a speed of 20 km/h. Another boat has been heading due east at 15 km/h and reaches the same dock at 8:00 P.M. How many minutes after 7:00 P.M. were the two boats closest together? Round your answer to the nearest minute.
boat moves in the same direction as....? A river current has a velocity of 5 km/h relative to the shore, and a boat moves in the same direction as the current at 5 km/h relative to the river. How can the velocity of the boat relative to the shore be calculated?
A. by multiplying the vectors
