Calculate the work needed for a 65 kg person to climb through 4.0 m

1 answer:

3 0

Work done = mgh; m = 65 kg, h = 4 m

a) g on Earth = 9.81 m/s²
W = 65 x 9.81 x 4
= 2550 Joules

b) g on moon = 1.62 m/s²
W = 65 x 1.62 x 4
= 420 Joules

Answer:

Height of coffee mug = 5 cm

Explanation:

Changing all the data given in to unit cm

50 mm = 5 cm

20 cm = 20 cm

8 m = 800 cm

0.1 km = 100 m = 10000 cm

Since we need to find the height of coffee mug, it's height will not be more than 10 cm.

So 5 cm is the correct choice.

The highest barrier that a projectile can clear is 19.7 m, when the projectile is launched at an angle of 15.0o above the horizo

svlad2 [7]

Answer:

76 m /s

Explanation:

maximum height, H = 19.7 m

Angle of projection, θ = 15 degree

Let u be the projectile launch speed

Use the formula of maximum height

$H = u^{2}Sin\theta ^{2}/2g$

$19.7 = u^{2}Sin^{2}15/19.6$

u = 75.9199 = 76 m /s
