A boy sits on a boat in a lake. In his boat he has a pile of rocks, each with mass 0.538 kg. He throws the rocks off the back of

Viktor [21]

Answer:

6.47385 N

Explanation:

m = Mass of stone = 0.538 kg

t = Time taken to hit the rock = 0.964 seconds

v = Velocity of rock = 11.6 m/s

Force is given by

$F=\frac{mv}{t}\\\Rightarrow F=\frac{0.538\times 11.6}{0.964}\\\Rightarrow F=\frac{6.2408}{0.964}\\\Rightarrow F=6.47385\ N$

The magnitude of the average force experienced by the boat during this process is 6.47385 N

What height would a 4 kg book need to be to have a potential energy of

zloy xaker [14]

Answer:

5.99 m = 6 m

Explanation:

PE = m*g*h

235.2 J = (4 kg)(9.81 m/s^2)(h)

h = (235.2 J)/(9.81*4)

h = 5.99 m

h = 6 m

What was the maximum speed of the car in your experiment?

MA_775_DIABLO [31]

The measurements used in the experiment is the amount of speed over time.

The measurement of speed is indicated along the “y” axis.

Upon viewing the graph, the highest point along the “y” axis shown is 25 m/s. This would be the maximum.

The maximum speed of the car would be 25 m/s.
