Explanation:
A rock is thrown upward with a speed of 2.0m/s.
a. How long will it take the rock to reach the peak?
b. What is the maximum height it can reach?
Answers
Hi there!
(A)
When the rock reaches the peak, it will have a vertical velocity of 0 m/s. We can use the equation:
vf = vi + at
vf = final velocity (0 m/s)
vi = initial velocity (2 m/s)
a = acceleration (in this situation, due to gravity = 9.8 m/s²)
t = time (s)
0 = 2 + (-9.8)t
2/9.8 = t = .204 sec
(B)
Use the equation:
d = vit + 1/2at²
d = 2(.204) + 1/2(-9.8)(.204²)
d = .204 m
An object is thrown upwards with a velocity of 15 m/s. How long will the ball take to reach it’s starting point ?
Answers
Answer:
about 2s or 3s,
Explanation:
15 m/s - 9.8 m/s = 5.2 m/s (1 sec)
5.2 m/s - 9.8 m/s = -4.6 m/s (2 sec)

what is the rotational kinetic energy of the earth? assume the earth is a uniform sphere. data for the earth can be found inside the back cover of the book.
Answers
The rotational kinetic energy of the earth is 2.587 × 10²⁹ J
The rotational kinetic energy of the earth is given by K = 1/2Iω² where I = rotational inertia of earth = 2MR²/5 where M = mass of earth = 5.972 1× 0²⁴ kg and R = radius of earth = 6.4 × 10⁶ m. ω = angular speed of earth = 2π/T where T = period of earth = 24 hours = 24 × 60 × 60 = 86400 s = 8.64 × 10⁴ s
So, K = 1/2Iω²
K = 1/2 × 2MR²/5 × (2π/T)²
K = 4π²MR²/5T²
Substituting the values of the variables into the equation, we have
K = 4π²MR²/5T²
K = 4π² × 5.972 × 10²⁴ kg × (6.4 × 10⁶ m)²/[5(8.64 × 10⁴ s)²]
K = 4π² × 5.972 × 10²⁴ kg × 40.96 × 10¹² m²/[5(74.6496 × 10⁸ s)²]
K = 4π² × 244.61312 × 10³⁶ kgm²/373.248 × 10⁸ s²
K = 9656.93890286 × 10³⁶ kgm²/373.248 × 10⁸ s²
K = 25.87 × 10²⁸ kgm²/s²
K = 2.587 × 10²⁹ J
So, the rotational kinetic energy of the earth is 2.587 × 10²⁹ J

– What is the tangential speed of the discus at release?
– What is the centripetal acceleration of the discus?
– What is the centripetal force on the discus?
giving Brainliest for full and proper answers! thank you for anyone who tries to help/explain :)
Answers
(a) The tangential speed of the discus at the release is 15 m/s.
(b) The centripetal acceleration of the discus is 225 m/s².
(c) The centripetal force on the discus is 360 N.
The given parameters;
mass of the discus, m = 1.6 kgradius of the path, r = 1 mangular speed, ω = 15 rad/stime of motion, t = 1.2 sThe tangential speed of the discus at the release is calculated as follows;
[tex]v = \omega r\\\\v = 15 \ rad/s \ \times 1 \ m\\\\v = 15 \ m/s[/tex]
The centripetal acceleration of the discus is calculated as follows;
[tex]a_c = \frac{v^2}{r} \\\\a_c = \frac{15^2}{1} \\\\a _c = 225 \ m/s^2[/tex]
The centripetal force on the discus is calculated as follows;
