I know that I need to convert 77 km/h to 21. 38888889 m/s which is the initial Velocity.
I was thinking of finding T with the equation d=V(initial)*T. So i could therefore put it in the question in: d=V(initial)*T + 1/2at^2 and solve for a.
However, I am unsure if I use 103m or 107 m in the...
A train is moving parallel and adjacent to a highway with a constant speed of 31 m/s. Initially a car is 49m behind the train, traveling in the same direction as the train at 43 m/s and accelerating at 3 m/s/s.
What is the speed of the car just as it passes the train?
Answer in units of...
A driver in a car traveling at a speed of 77 km/h sees a cat 107 m away on the road. How long will it take for the car to accelerate uniformly to stop in exactly 103m? Answer in units of s.
I really have no idea where to begin with this problem.
A highway curves to the left with radius of
curvature R = 46 m. The highway’s surface
is banked at θ = 26 so that the cars can take
this curve at higher speeds.
Consider a car of mass 1018 kg whose
tires have static friction coefficient µ = 0.57
against the pavement.
The acceleration...
There is friction between the block and the table.
The suspended 4 kg mass on the left is moving up, the 2 kg mass slides to the right on the table, and the suspended mass 7 kg on the right is moving down. The acceleration of gravity is 9.8 m/s/s. What is the magnitude of the acceleration of...
Homework Statement
An airplane in a wide "outside" loop can create an apparent zero eight inside the aircraft cabin. What must be the radius of curvature of the flight path for an aircraft moving at 749 km/h to create a condition of weightlessness inside the aircraft? Assume the acceleration...
