A car starts from rest and goes down a slope with a constant acceleration of 5 m/s².After 5 seconds the car reaches the bottom of the hill.What is its speed at the bottom of the hill? A)1 m/s B)12.5 m/s C)25 m/s D)50 m/s E)160 m/s

Question

Quizplus · Accepted Answer

The speed of the car can be calculated using the formula v = u + at, where u is the initial velocity (0 m/s), a is the acceleration (5 m/s²), and t is the time (5 s). Thus, v = 0 + (5 m/s²)(5 s) = 25 m/s.
