Question

Aif v = u +at , find v when u = 2, a = 1/2 and t = 4

Answer 1

Step-by-step explanation:

We know that,

V= U+at

by putting their values, we get

V= 2+½×4

V=2+2

V= 4m/s

So, the value of V is 4m/s.

Answer 2

Step-by-step explanation:

Acceleration is the rate of change of velocity of an object. where a is acceleration, v is the final velocity of the object, u is the initial velocity of the object and t is the time that has elapsed. This equation can be rearranged to give: v = u + at.

u = 2 m/s

a = 1/2 m/s^2

t = 4 sec

v = 2 + (1/2 × 4)

v = 2 + 2

v = 4 m/s
