Answer: 3,000 N

Explanation:

F = mass x acceleration

F = (1500 kg)(2 m/s²)

F = 3000 N

Please help me! I don't understand how to do this!
dezoksy [38]

From the information in the question, the acceleration of the cart is 2.55 ms-2.

We can find the acceleration using the following information from the question;

u = 0.9 m/s

v = 6 m/s

a =  2.0 seconds

But;

a = v - u/t

v = final velocity

u = initial velocity

t = time

a = 6 - 0.9/2 = 2.55 ms-2

Force= ma

m = mass

a = acceleration

F = 6 kg × 2.55 ms-2

F = 15.3 N

With a quick flick of her wrist, an Ultimate Frisbee player can give a Frisbee an angular velocity of 4.00 revolutions per secon
Ad libitum [116K]

Answer:

a) w = 25.1 rad/s, b) θ  = 0.9599 rad , c) α = 328.1 rad/s²  d) t=  0.0765 s

Explanation: Let's work on this exercise with the equations of angular kinematics

a) The angular velocity is

    w = 4.00 rev / s (2π rad / 1 rev)  

     w = 25.1 rad/s

b) let's reduce the angle of degrees to radians

    θ = 55 ° (π rad / 180 °)

    θ  = 0.9599 rad

c) Let's use the initial angular velocity as the system part of the rest is zero

    w² = w₀² + 2 α θ

    α = w² / 2 θ

   α = 25.1²/2 0.9599

   α = 328.1 rad / s²

d)

   w = w₀ + α t

    t = w / α

    t = 25.1 / 328.1

    t=  0.0765 s

Air escapes from a balloon at a rate of 2 60 ( ) 1 R t t   3 ft / min , where t is measured in minutes. How much air (in 3 ft
kotykmax [81]

Answer:

Given R (t) = 60/(1+t²), ft /min

To find the amount of air in ft³, during the first min,

R (t) = 60/(1+t²

at t=1min, R is the air amount in ft³/min

Take the integral, and evaluate over [0,1]

Integral Of R (t) = 60/(1+t²) = 60 tan⁻¹(t),

60(Tan⁻¹(1) - Tan⁻¹(0)) = 60(pi/2) = 30 π

Therefore, it means that in the first minute, 30π ft³ of air escaped.
