Answer:

Explanation:

Near the earth's surface where gravity is approximately 10 m/s² downward

v = u + at

v = 5 + (-10)(1) = -5 m/s

so it has the same speed but in the opposite (downward) direction.

<h3>Answer:</h3>

80 kgm/s

<h3>Explanation:</h3>

<u>We are given;</u>

Mass of the Canoe is 32 kg
Speed of the Canoe is 2.5 m/s

We are required to calculate the momentum of the Canoe?

We need to know that momentum is the product of mass of an object and its speed.

Therefore;

Momentum = Mass × speed

Therefore;

Momentum = 32 kg × 2.5 m/s

= 80 Kgm/s

Thus, the momentum of the Canoe is 80 kgm/s.
