A ball of 1.2kg with velocity 4ms-1 hit by a car which moving in same direction with the ball. the velocity of the ball increase to 10ms-1 in 0.5s. what is the impulse on the ball?

Explanations & Calculations
Impulse is defined as the product of force & the time during which that force is applied.
With the collision both the objects experience a mutual impulse which causes any increment or decrement in their velocities.
As it's been stated, that impulse has increased it's velocity.
In simplified form the relationship is written,
I=Ft=Δmv=mΔv
Therefore, applying that along the moving direction, impulse could be found as follows.
