**Answer:**

James is correct here as the force of hand pushing upwards is always more than the force of hand pushing down

**Explanation:**

Here we know that one hand is pushing up at some distance midway while other hand is balancing the weight by applying a force downwards

so here we can say

Upwards force = downwards Force + weight of snow

while if we find the other force which is acting downwards

then for that force we can say that net torque must be balanced

so here we have

so here we have

so here we can say that upward force by which we push up is always more than the downwards force

**Answer:**

**Explanation:**

Momentum is equal to mass times velocity in kg and m/s, respectively. Therefore,

p = 100(15) so

p = 1500

+ 1.58 e -15
