Question

an object Ras uniformly accepeated motion. what will be the velocity-time graph when,
(a) both u and a are +ve
(b) u= -ve, a=-ve
(c) u=+ve and a=-ve
(d) both u2 a are -ve​

Answer 1

Answer:

prefer to it child

Explanation:

Consider a body of mass m, having a initial velocity u. After time t, its velocity becomes v due to uniform acceleration a.

Since, Acceleration= FinalVelocity−InitialVelocity/time

Therefore, a= v−u/t

Hence, v=u+at
