The value of t when the block comes to rest is most nearly 0.5 s.
The given equation of motion;
x(t) = Mt - Nt²
The given units of M and N are;
<em>M ------> m/s</em>
<em>N -------> m/s²</em>
When the block comes to rest the final velocity of the block will be zero.
Velocity is change in displacement per change in time.
Thus, the value of t when the block comes to rest is most nearly 0.5 s.

Answer:
The momentum of the bowling ball is 40 kg m/s.
Explanation:
Momentum is defined as the product of mass and velocity acting on that object. So it is a measure of the change in the velocity for the given force with the mass of the object.
Momentum = Mass × Velocity.
As the mass of the object is given as 5 kg and the velocity is given as 8 m/s, then the momentum will be
Momentum = 5 kg × 8 m/s = 40 kg m/s.
So, the momentum of the bowling ball is 40 kg m/s.
