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...
