Answer:
(a). The mass of the block of ice is 62.8 kg.
(b). The distance is 24.192 m.
Explanation:
Given that,
Horizontal force = 80.5 N
Distance = 13.0 m
Time = 4.50 s
(a). We need to calculate the acceleration of the block of ice
Using equation of motion
Put the value into the formula
We need to calculate the mass of the block of ice
Using formula of force
Put the value into the formula
(b). If the worker stops pushing at the end of 4.50 s,
We need to calculate the velocity
Using equation of motion
Put the value into the formula
We need to calculate the distance
Using formula of distance
Put the value into the formula
Hence, (a). The mass of the block of ice is 62.8 kg.
(b). The distance is 24.192 m.
