Minchanka [31]4 years ago

Answer:

explained

Explanation:

A Good scientific question must lead to a hypothesis and must help in answering the reason for any observation. It should be testable, meaning it can be performed as an experiment. At the same time the formed hypothesis can be falsifiable, that is it can fail. For example, the sound generated by a moving car. The question can be is there any correlation between speed of car and the noise it generate. It can result in a hypothesis that at higher speed more noise occur. It can very easily tested.

Charlie Brown kicks a football at 24.5 m/s at 35.0. What is the maximum height of the ball?
lozanna [386]

Answer:

d = 10.076 m

Explanation:

We need to obtain the velocity of the ball in the y direction

Vy  = 24.5m/s * sin(35) = 14.053 m/s

To obtain the distance, we use the formula

vf^2 = v0^2 -2*g*d

but vf = 0

d = -vo^2/2g

d = (14.053)^2/2*(9.8) = 10.076 m

A 67 kg kg driver gets into an empty taptap to start the day's work. The springs compress 2.3×10−2 m m . What is the effective s
amid [387]

Point of correction, spring constant is 2.3×10−2 m not 2.3×10−2 m m

Answer:

28577 N/m

Explanation:

From Hooke's law, F=kx where F is force applied, k is spring constant and x is compression

F=mg=67*9.81

k=\frac {mg}{x}

k=\frac {67*9.81}{2.3\times 10^{-2}}=28576.95652 N/m

Approximately, 28577 N/m
