The centripetal acceleration (
)
is given by
Where v is the velocity of the object, and r is the radius of the circle.
2. The initial centripetal acceleration of the car was
It is given that the velocity of the car and the radius of the track gets doubled. So, the new centripetal acceleration of the vehicle is
Hence, the centripetal acceleration will also get doubled.
3. The speed of the jet is 200 m/s, and the radius of the track of the plane is 1000 m.
So, the centripetal acceleration of the jet is
The acceleration due to gravity is 10 m/s2 .
Hence, the centripetal acceleration of the jet is four times greater than the acceleration due to gravity.

10) When a car makes a turn at a constant velocity, on a flat level road, does the car experience a net force while making the turn? (Be careful Canvas my not have the same order for the answers) No, because the frictional force is equal to the centripetal force. No, because the speed is constant. Yes, it is the frictional force and is directed towards the center Yes, it is the frictional force and is directed outward away from...

1. A car accelerates from zero to 105 km/h in 5.21 s. What is its average acceleration in km/h/s and m/s? 2. An object moving in the x-direction has a position described by the function x(t) - 6.30t + 8.70t2, where t is in seconds and x is in meters. What is the acceleration as a function of time? The figure shows the graph of v vs t for the motion of a motorcyle that starts from rest and moves...

Lab 4: Introduction & Instructions Centripetal Acceleration Introduction Velocity is a vector with both a magnitude and a direction. Since acceleration is a measure of a change in velocity over time, it seems reasonable that either the magnitude of the velocity vector could be changing, or the direction, or both. If magnitude is changing only, then the motion occurs in one dimension and the principles of algebra can be applied to the equations of motion. But suppose the opposite case...

Problem 1: A car of mass 1000 kg moves at a constant speed of 20 m/s along a horizontal road where a frictional force is 200N. Calculate the power developed by the engine. If the car now moves up an incline at the same constant speed, calculate the new power developed by the engine. Assume that the frictional force is still 200 N and that sin(theta)=1/20 where theta is the angle of the incline to the horizontal. Problem 2: An...
