Read image pls A jet transport with a landing speed of 200 km/hr reduces its speed to 60 km/hr with a negative thrust R from its jet thrustreversers in a distance of 410 m along the runway with constant deceleration. The total mass of the aircraft is 135 Mg withmass center at G. Compute the reaction N under the nose wheel B toward the end of the braking interval and prior to theapplication of mechanical braking. At the lower speed, aerodynamic forces on the aircraft are small and may be neglected.G2.6 mB14 m.R1.6 mA-2.5 mN = 0kN

First, we need to convert the speeds from km/hr to m/s because the other measurements are given in…

2/100 The driver of the truck has an acceleration of 0.4g as the truck passes over the top A of the hump in the road at constant speed. The radius of curvature of the road at the top of the hump is 98 m, and the center of mass G of the driver (considered a parti- cle) is 2 m above the road. Calculate the speed u of the truck.

Each tire on the 1425-kg car can support a maximum friction force parallel to the road surface of 2170 N. This force limit is nearly constant over all possible rectilinear and curvilinear car motions and is attainable only if the car does not skid. Under this maximum braking, determine the total stopping distance s if the brakes are first applied at point A when the car speed is 18 m/s and if the car follows the centerline of the road.
If the car decelerates uniformly along the curved road from 29.4 m/s at A to 13.2 m/s at C, determine the acceleration of the car at B. L = 237 m L2 = 76 m Рв - 280 m L1 L2 PB
Car B is towing car A at a constant speed of 10 m/s on an uphill grade when the brakes of car A are fully applied causing all four wheels to skid. The driver of car B does not change the throttle setting or change gears. The masses of the cars A and B are 1400 kg and 1200 kg, respectively, and the coefficient of kinetic friction is 0.8. Neglecting air resistance and rolling resistance, determine (a) 5m 10 m/s 10 m/s the distance traveled by the cars before they come to a stop, (b) the tension in the cable.

Estimate the power requires to accelerate a 1350 kg vehicle traveling at 48 kph up a 5% grade at the rate of 1.8 m/sec². The roadway has a straight alignment and a badly broken and patched asphalt surface. Rolling resistance of vehicle is 167 N/metric-ton, Air density = 1.2 kg/m³, and Aerodynamic drag coefficient = 1.3. Express power in watts using the formula P = RV. Use the formula for:

In a certain situation it was estimated that 24.9% of the braking force was applied to the rear brakes in order for the car to develop the maximum forces required stop the car. If the total braking force develop was 5565 N and the road is wet (u = 0.6) wheel base of 295 cm and a center of gravity 75 cm above the pavement road and 120 cm behind the front axle. What was the speed of the car in kph?
A banked circular highway curve is designed for traffic moving at 63 km/h. The radius of the curve is 204 m. Traffic is moving along the highway at 45 km/h on a rainy day. What is the minimum coefficient of friction between tires and road that will allow cars to take the turn without sliding off the road? (Assume the cars do not have negative lift.) n on Number i Units
The 5-Mg truck and 2-Mg car are traveling with the free-rolling velocities of 37 km/h and 13 km/h, respectively, just before they collide. After the collision, the car moves with a velocity of 13 km/h to the right relative to the truck. Determine the coefficient of restitution between the truck and car.
A four-wheel vehicle of mass 1000 kg moves uniformly in a straight line with the wheels revolving at 10 rad/s. The wheel are identical, each with a radius of 0.2 m. then a constant braking torque is applied to all the wheels and the vehicle experiences a uniform deceleration. For the vehicle to stop in 10s, the braking torque (in N. m) on each wheel is
