Answer:11.5 s plus or minus 0.196 s

Explanation:

The uncertainty in the time of the runner to complete the distance is 11.5 s ± 0.1955 s

The given parameters;

length of the track, d = 100 m

time to complete the track, t = 11.5 s

the uncertainty, = 1.7%

The uncertainty in the time of the runner to complete the distance is calculated as;

the uncertainty = ± (0.017 x 11.5)

the uncertainty = ± 0.1955 s

Thus, the uncertainty in the time of the runner to complete the distance is 11.5 s ± 0.1955 s

VladimirAG [237]

Answer:

1.53 s

Explanation:

Initially vertical component of velocity of the ball, uy = 7.5 m/s

Net displacement is vertical direction is zero, Δy =0

Use second equation of motion:

Δy = uy t + 0.5 a t²

Here, acceleration a = -g                           (g =9.8 m/s²)

Substitute all the values and solve for g

0 = 7.5 t -0.5 (9.8)t²

7.5 t = 4.9 t²

t = 1.53 s

he cans have essentially the same size, shape, and mass. Which can has more energy at the bottom of the ramp
stepladder [879]

Answer:

c. both have same energy

Explanation:

The complete question is

suppose you have two cans, one with milk, and the other with refried beans. The cans have essentially the same size, shape, and mass. If you release both cans at the same time, on a downhill ramp, which can has more energy at the bottom of the ramp? ignore friction and air resistance..

a. can with beans

b. can with milk

c. both have same energy

please explain your answer

Since both cans have the same size, shape, and mass, and they are released at the same height above the ramp, they'll possess the same amount of mechanical energy. This is because their mechanical energy, which is the combination of their potential and kinetic energy are both dependent on their mass. Also, having the same physical quantities like their size and shape means that they will experience the same environmental or physical factors, which will be balanced for both.
