A sports car of mass 950 kg (including the crosses the rounded top of a hill (radius = 95 m) at 22 Determine the normal force exerted by the road the car, the normal force exerted by the car on 72-kg driver, and the car speed at which the force on the driver equals zero.
A 1000 kg car enters a curve in the (unbanked) road. The driver finds that the top speed at which he can make the bend without skidding is 18 m/s. a. Make a free-body diagram of the car in the r-z plane. b. What is the radius of the circle of which the curve is a part? (s = 0.8, k = 0.5) c. Calculate the centripetal force on the tires of the car.
A car drives over a rounded hill. A) What is the fastest the car can go, in m/s, without the tires coming off of the road? B) If the mass of the car is 1500 kg, what is the net force on the car when it is at the top of the hill when it travels at a speed of 5 m/s?
4. A 76-kg car driver reaches the bottom of a hill moving at a speed of v= 20 m/s. This bottom of the hill forms the arc of a circle whose radius is 200 m, as shown. (a) At this bottom of the hill, what is the magnitude /r = 200 m of the centripetal acceleration of the driver? (b) Find the force exerted on the driver by the car seat at this bottom of the hill. [(a) 2 m/s;...
A roller-coaster car has a mass of 660 kg when fully loaded with passengers. The car passes over a hill of radius 15 m, as shown. At the top of the hill, the car has a speed of 8.2 m/s. What is the force of the track on the car at the top of the hill?
3. An engine exerts a force of 10000 N on a 1000 kg car travelling over a flat road. The force (overcoming friction) accelerates the car from rest such that it travels a distance of 50 m in 5 s Find e. the net acceleration of the car, f. normal force exerted by the road on the car, and g. the coefficient of kinetic friction between the car and the road? 4. A 10 kg block is initially at rest...
A roller-coaster car has a mass of 500 kg when fully loaded with passengers. The car passes over a hill of radius 15 m, as shown. At the top of the hill, the car has a speed of 8.0 m/s. What is the force oof the track on the car at the top of the hill?
A roller-coaster car has a mass of 1040 kg when fully loaded with passengers. As the car passes over the top of a circular hall of radius 18 m, its speed is not changing. (a) At the top of the hill, what is the normal force (using the negative for the downward direction) on the car from the track if the car's speed is v = 7.4 m/s? (b) What is if v = 17 m/s? Use g = 9.81...
8) A roller-coaster car has a mass of 1780 kg when fully loaded with passengers. The car passes over a hill of radius 15 m, as shown. At the top of the hill, the car has a speed of 17.9 m/s. What is the force of the track on the car at the top of the hill? 15 m
A 1100 kg car traveling at 20 m/s goes over a hill. At the top, the hill provides an upward normal force of 5600 N. (a) Assuming the hill has a circular profile, find the radius of curvature of the hill. (b) What is the maximum speed the car can go over the hill without ramping the car off the ground?
