3 0

Answer:

2.25 seconds

Explanation:

Change in Acceleration = change in velocity / time interval

time interval = change in velocity / change in acceleration

                    = (9 - 0) / (0 - -4) = 9/4

                    = 2.25 seconds

Ted lifts a 10N weight at a height of 1.5 m in 1
masha68 [24]

Answer:

D. Ted expanded more power.

Explanation:

Given the following data;

For Ted.

Force = 10N

Height = 1.5m

Time = 1 seconds

To find Ted's power;

Power = workdone/time

But workdone = force * distance

Workdone = 10 * 1.5

Workdone = 15 Nm

Power = 15/1

Power = 15 Watts.

For Johnny.

Force = 10N

Height = 1.5m

Time = 2 seconds

To find Ted's power;

Power = workdone/time

But workdone = force * distance

Workdone = 10 * 1.5

Workdone = 15 Nm

Power = 15/2

Power = 7.5 Watts

Therefore, from the calculations we can deduce and conclude that Ted expanded more power.
