43.5 kg. Shawn rides his bike 1.3 km in

Physics
1 answer:
Alexeev081 [22]3 years ago
6 0

Answer:

K.E is 90.625 J

Explanation:

Data:

Mass = m = 43.5kg

Distance = d = 1.3km = 1300 m

Time = t = 10.4 min = 624 sec

Accelaration = a or g = 9.8

Formula for kinrtic energy

K.E = 1/2mv²

Find velocity

V = d/t = 1300/624 = 2.0833333333333 m/s

Put values in formula

K.E = 1/2 (43.5)(2.084)² = 90.624999999995

Light travels at a speed of 2.998*108 m/s. Light takes approximately 3.25 minutes to travel from the Sun to reach a planet. Calc
ANTONII [103]

Answer:

585×10⁸ m

Explanation:

Distance = rate × time

d = (2.998×10⁸ m/s) (3.25 min) (60 s/min)

d = 585×10⁸ m

A 5 kg block is pushed across a table by a horizontal force of 40 N with an acceleration of 5 m/s^2. What is the frictional forc
julsineya [31]

Answer:

15

Explanation:

mass, M = 5Kg

horizontal force, F_h = 40N

acceleration, a =5 m/s^2

frictional force, F_f =?

net force = ma

net force = F_h - F_f = 40N - F_f

40  - F_f = 5 x 5

- F_f = 25 - 40

multiply both side by -1

F_f = 40 - 25 = 15

the frictional force is 15N

This circuit has five bulbs (A, B, C, D, and E). Select which bulbs would turn off if bulb C was unscrewed.
LiRa [457]

Answer:

C, A and E

Explanation:

In theory you always assume that the prostive is going to the negtive and since C, A and E are in series they all will turn off will turn off
