Some cars take 10 seconds to accelerate 100 km/h while
stationary. Assuming the vehicle's speed is constant, find the
acceleration of this vehicle and the mileage for 10 seconds.
A stationary police car is passed by a driver driving at a constant speed of 130 km / h. The police officer catches the fast-moving driver after 750 m at constant acceleration.
a) Draw a plot of position time over the period of action of each vehicle.
b) How soon will the police car catch the driver?
c) The acceleration required for the police car
d) What is the speed of the police car at the point of capture?
A curve of radius 90 m is banked for a design speed of 100 km/h.
If the coefficient of static friction is 0.30 (wet pavement), at
what range of speeds can a car safely make the curve?
A curve of radius 70 m is banked for a design speed of 100 km/h
. If the coefficient of static friction is 0.33 (wet pavement), at
what range of speeds can a car safely make the curve?
An airplane is heading due south at a speed of 680 km/h .
A. If a wind begins blowing from the southwest at a speed of 90
km/h (average), calculate the velocity (magnitude) of the plane
relative to the ground.
B. Calculate the velocity (direction) of the plane relative to
the ground.
C. Calculate how far from its intended position will it be after
18 min if the pilot takes no corrective action.
Train driving 5 % uphill (2.9o) with speed 120 km/h.
Train total mass is 100 000 kg. The gear ratio is 1 (no
transmission) and the train wheel diameter is 1 m. (Give the answer
of accuracy of at least three significant digits.) Calculate the
required torque: Answer kNm Calculate the required power:
A sports car of mass 1000 kg can accelerate from rest to 72.
km/h in 6.6 s.
a) What would the average force of the car's engine be?
b) If the same force acts on 2000 kg car what is the
acceleration.
An airplane is flying at an air speed of 420 km/h on a heading
of 210o. A 45 km/h wind is blowing from a bearing of
50o. Determine the bearing and ground velocity of the
airplane using geometric vectors.
Please include what equation we are trying to solve for, thank
you in advance~!
A pilot on a heading of 320o with an air speed of 240
km/h. Her actual ground velocity is 250 km/h at a bearing of
318o. Calculate the speed and direction of the wind.
Please include the equation we are trying to solve values for as
I get confused easily! Thank you in advance.
A curve of radius 69 m is banked for a design speed of 78 km/h.
If the coefficient of static friction is 0.30 (wet pavement), at
what range of speeds can a car safely make the curve? [Hint:
Consider the direction of the friction force when the car goes too
slow or too fast.]
