Given: The train engine at E has a speed of 20 m/s and an acceleration of 14 m/s² acting at v = 20 m/s in the direction shown. a = 14 m/s? а. Find: The rate of increase in the train's speed and the radius of curvature p of the path. Plan: 1. Determine the tangential and normal components of the acceleration. 2. Calculate v from the tangential component of the acceleration. 3. Calculate p from the normal component of the acceleration.

Answer a and  c

1. Refer to figure 1. A spherical shell and solid sphere roll down a ramp with a 30.0° inclination. Calculate the final velocities of each sphere when they reach the bottom and the velocity of each sphere ½ the distance above the ground. 20.0m Solid sphere, about diameter Spherical shell, about diameter R MR² MR²

How do you get part C

Find radial acceleration, tangential acceleration and acceleration shown in picture.

The figure below shows a car traveling in a counterclockwise along a circular path.  If the radius of curvature of the road is 87 m and the speed of the car is 13 m/s, determine the centripetal acceleration of the car.

1. A stopwatch starts while race car travels at 13 m/s from the pit area and accelerates at a uniform rate to a speed of 37 m/s in 5 s moving on a circular track of radius 548 m. Assuming constant tangential acceleration, find (a) the tangential acceleration, and (b) the radial acceleration,at the instant when the speed is v=7 Once you have both of those…. find the magnitude of a at any moment a= 2. A stopwatch starts while race car travels at 5 m/s from the pit area and accelerates at a uniform rate to a speed of 23 m/s in 16 s moving on a circular track of radius 466 m. Assuming constant tangential acceleration, find (a) the tangential acceleration, and (b) the radial acceleration,at the instant when the speed is v=15 Once you have both of those …. find the magnitude of a at any moment a= 3. A stopwatch starts while race car travels at 7.0 m/s from the pit area and accelerates at a uniform rate to a speed of 22 m/s in 3 s moving on a circular track of radius 491 m. Assuming constant…

please help ASAP (& pls draw a picture), thank you!

please do part c
