A skiy diver, with parachute unopened, falls 625 m in 15.0s.

Physics
1 answer:
olganol [36]2 years ago
3 0

Answer:

average velocity = 6.25m/sec

Explanation:

given data:

for unopened

height = 625 m

time  = 15 sec

for opened

height = 356 m

time =  142 sec

Unopened:

V1 = \frac{625\ m}{15\ sec} = 41.67m/sec

Opened:

V2 = \frac{356\ m}{142\ sec} = 2.51m/sec

we know that

Total Average Velocity= \frac{Total\ distance}{Total\ time}

average velocity= \frac{981\ m}{157\ sec}

average velocity = 6.25m/sec

A mover does 422 J of work pushing a crate 8.39 m. How much force did he exert?
kicyunya [14]

Answer:

50.3N

Explanation:

Work done = force x distance

422J. = force x 8.39m

÷8.39 both side to get force

Force is 50.3N to 1 d.p.

Check:

50.3 x 8.39=422.017J

Same as 422J to 1 d.p

the distance between two points P and Q is 120 m a object goes from point P to q and then returned to P in 1 minute 40 second wh
Naily [24]

Answer:

using a formula

average velocity=total displacement/total time

average velocity=120/1minute40sec

1minute=60sec

60sec+40sec=120sec

average velocity=120m/120sec

average velocity=1m/sec
