A 23.3 kg crate is pushed with a force of 944 N for 36.0 seconds, moving the crate a distance of 12.4 m. How much power was used
tigry1 [53]

Explanation:

p  =  \frac{f \times s}{t}

power = Force × distance /time

power = 944N × 12.4m/36secs

power = (944×12.4/36)Nms—¹

power = 390.2Nms—¹ or 390.2Watts or 390.2Js—¹

A ball is thrown straight up. It passes a 2.00-m-high window 7.50 m off the ground on its path up and takes 1.30 s to go past th
OLga [1]

Answer:

u =  13.67 m/s

Explanation:

given,

window height = 2 m

window is 7.5 m off the ground on its path up

total distance from the ground to pass the window = 2 + 7.5 = 9.5 m

time taken to go past the window = 1.30 s

using equation of motion

S = u t +\dfrac{1}{2}gt^2

(2+7.5)= u\times 1.3 -0.5\times 9.8\times 1.3^2

u\times 1.3 = 9.5 + 8.281

u =  13.67 m/s

hence, the initial velocity of the  ball is equal to 13.67 m/s
