Question

a ball is thrown vertically upwards which of the following graph represent velocity time graph of the ball during its flight​

Answer 1

(D)

When a ball is thrown upwards, it has a constant negative acceleration of g.

Therefore, slope of v-t graph i.e. dv/dt= -g

since slope is constant and negative throughout, graph D is correct.

Answer 2

Answer:

D

Explanation:

From the pic it should have a intercept so opt c is neglected

Again during the upward motion it's velocity continuously decreases but during downward motion it's velocity increases but in negative direction. Hence optD is right. BUT if they mentioned SPEED opt A should be right because direction shouldn't be considered
