2. A body starts with an initial velocity of 10 m s-1 and acceleration 5 m s2. Find the distance covered by
it in 5 s.

112.5 m

Explanation:

d = vo . t + ½ a t²

d = distance

vo = initial velocity

t = time

a = acceleration

d = 10 . 5 + ½ . 5 . 5²

d = 50 + 62.5

d = 112.5 m

d.7.5cm is your answer

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
