John coasts on his skateboard at a speed of 4 m/s. he uses his foot to increase his speed to 5 m/s. if he has a mass of 103 kg, what impulse does he apply

Impulse = 103 kg m/s

Explanation:

As we know that impulse is defined as change in momentum

So here we will have

here final speed is 5 m/s after he use his foot while his initial speed is given as 4 m/s

now we will have

initial momentum is given as

now impulse is given as

statement #3 on andre"s list is false.
