Answer:
1.5 unit of product per min
Explanation:
30 units of product was moved in 30 minutes.
Number of units left = Total number of units-number of units moved
=75-30 =45 units
45 units is available to be moved for the rest 30 min. To be able to achieve this goal of 75 units of product per hour.
45/30 amount of units must be moved in 1 min
=1.5 unit per min
Answer:
v after 5s = 0.25 m/s, it took 10s to stop, it has traveled 2.5m before stopping
Explanation
We can use the equation of motion with constant acceleration
Given: v0= 0.5 m/s a= -0.05 m/s²
v(5s) = v0 + a×t = 0.25 m/s
Stop => v=0 => v0 + a×t = 0 => t=10s
Distance at t=10s ⇒ x(10) = 0.5×10 + 0.5x(-0.05)x10² = 2.5m
Choice 'b' is one possible way to state
Newton's second law of motion.
The other choices are meaningless.
The answer is B 1,500 meters since 1 kilometer to meters is 1,000 and u add the 500
