A ball starts from rest and accelerates at 0.460 m/s2 while moving down an inclined plane 8.85 m long. When it reaches the bottom, the ball rolls up another plane, where, after moving 15.6 m, it comes to rest. What is the speed of the ball at the bottom of the first plane

Explanation:

From the question we are told that

Acceleration

Distance traveled

Distance traveled

Generally the velocity of the ball at the bottom of the first plane V is mathematically given by

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
