Car A and B start a race from rest. Car A starts with an acceleration of 100 m/s^2 and after 10s increases with acceleration to 200 m/s^2. Car B starts with an acceleration of 50 m/s^2 and after 5s increases the acceleration to 300 m/s^2. 1) What is the distance between cars after 1s 2) What is the velocity of each car after 1s 3) After 30 seconds which car is ahead?

(a) What is the tangential acceleration of a bug on the rim of a 6.0 in, diameter disk if the disk moves from rest to an angular speed of 79 rev/min in 5.0 s? 425 Your response differs from the correct answer by more than 100%, m/ s (b) When the disk is at its final speed, what is the tangential velocity of the bug? m/s (c) One second after the bug starts from rest, what is its tangential acceleration?...
16-25. The disk starts from rest and is given an angular acceleration a = (1001/3) rad/s?, where @ is in radians. Determine the magnitudes of the normal and tangential components of acceleration of a point P on the rim of the disk when t = 4 s. 0.4 m
A car starts from rest and travels for 10.0 s with a uniform acceleration of +1.8 m/s2. The driver then applies the brakes, causing a uniform acceleration of -2.5 m/s2. If the brakes are applied for 2.0 s, determine each of the following. (a) How fast is the car going at the end of the braking period? m/s (b) How far has the car gone? Om Need Help? Read It

Part A Learning Goal: To calculate the normal and tangential components of the acceleration of an object along a given path. A particle is traveling along the path y(x) = 0.3x2, as shown in (Figure 1), where y is in meters when x is in meters. When 3 = 5 m, the particle's velocity is v = 15 m/s and the magnitude of its acceleration is a = 11 m/s2 Determine the normal and tangential components of the acceleration What...
