Answer:
The mass of Laura and the sled combined is 887.5 kg
Explanation:
The total force due to weight of Laura and friction on the sled can be calculated as follows;
= (400 + 310) N
= 710 N
From Newton's second law of motion, "the rate of change of momentum is directly proportional to the applied force.
where;
is mass of Laura and
is mass of sled
Mass of Laura and the sled combined is calculated as follows;
given
V = Δv = 4-0 = 4m/s
t = 5 s
Therefore, the mass of Laura and the sled combined is 887.5 kg
