Question

Velocity-time graphs of two cars which start from rest at the same time, are shown in the figure. Graph shows that

• A. initial velocity of A is greater than the initial velocity of B
• B. acceleration in A is increasing at lesser rate than in B
• C. acceleration in A is greater than in B
• D. acceleration in B is greater than in A

Answer 1

The correct option is C acceleration in A is greater than in B

Slope is given by tan θ,

At a certain instant $t$, slope of A is greater than $B({\theta }_A>{\theta }_B)$, so acceleration in A is greater than B
