A deer with a mass of 146kg is running head on toward you with a speed of 17 m/s. You are going north. Find the momentum of the
2 answers:
Answer : The momentum of the deer is, 2482 kg.m/s
Explanation :
Momentum : It is defined as the motion of a moving body. Or it is defined as the product of mass of velocity of an object.
Formula of momentum is:
where,
p = momentum = ?
m = mass = 146 kg
v = velocity = 17 m/s
Now put all the given value in the above formula, we get:
Therefore, the momentum of the deer is, 2482 kg.m/s

Answer:
The final acceleration becomes (1/3) of the initial acceleration.
Explanation:
The second law of motion gives the relationship between the net force, mass and the acceleration of an object. It is given by :
m = mass
a = acceleration
According to given condition, if the mass of a sliding block is tripled while a constant net force is applied. We need to find how much does the acceleration decrease.
Let a' is the final acceleration,
m' = 3m
So, the final acceleration becomes (1/3) of the initial acceleration. Hence, this is the required solution.
