how long does it take a ball thrown straight upwards @ 10 m/storeach its maximum height (neglecting air resistance)?

the answer is 1 second, however please show me the steps to gettheanswer. the formula that was used was: v= vo + a(t)

but is v in this case and what is vo? please explainthanks!!!

a ball is thrown straight up with an initial speed of 30m/s. how high does it and how long is it in the air (neglecting air resistance)?

Determine the elastic potential energy stored in a spring with a spring constant of 125 N/m that is compressed 0.75 m.

A baseball is hit nearly straight into the air with a speed of22meters per second.

-How high does it go?

-How long is it in the air?

What is the difference between amphere and volt ?

A spring has a spring constant of 75 N/m. The spring is compressed15 cm and a 2 kg ball is placed on the spring in its compressedstate. When the spring is released, what is the kinetic energy ofthe ball as it leaves the spring?

What is the potential energy of the spring in its compressedstate?

What is the potential energy of the spring as the ball leaves thespring?

What is the total energy of the system(ball and spring) when thespring is compress? As the ball leaves the spring?

If a 0.4 kg baseball is traveling at 25 m/s straight into the air, how high does the ball go? Use energy to find the answer

How is physics worked into High jumping??

Physics work….?

Particle in xy plane The position r of a particle moving in an xyplane is given by
r = (2.00t3 - 3.00t) i + (7.00 - 2.00t4) j. Here r is in meters andt in seconds.

(a) Calculate r for t = 1.00 s.
______m i + ______m j + ______m k

(b) Calculate v for t = 1.00 s.
____m/s i + ______m/s j + _____m/s k

(c) Calculate a for t = 1.00 s.
______m/s^2 i + ______m/s^2 j + ______m/s^2 k
