3. A 70 kg person climbs a 6 m ladder. How much work is required by the person?

Physics
1 answer:
Lina20 [59]3 years ago
6 0

Answer:

4116J

Explanation:

Given parameters:

Mass of the person  = 70kg

Height of the ladder  = 6m

Unknown:

Work done  = ?

Solution:

The work done by the person climbing is the same as the potential energy.

Work done is the force applied to move a body through a distance;

So;

   Potential energy  = mass x acceleration due to gravity x height

Therefore;

    Potential energy  = 70 x 9.8 x 6   = 4116J

1. A baseball is thrown vertically at 16.7 m/s. What is the maimum height of the baseball?
Anvisha [2.4K]

Answer:

14.2 m

Explanation:

Using conservation of energy:

PE at top = KE at bottom

mgh = ½ mv²

h = v² / (2g)

h = (16.7 m/s)² / (2 × 9.8 m/s²)

h = 14.2 m

Using kinematics:

Given:

v₀ = 16.7 m/s

v = 0 m/s

a = -9.8 m/s²

Find: Δy

v² = v₀² + 2aΔy

(0 m/s)² = (16.7 m/s)² + 2 (-9.8 m/s²) Δy

Δy = 14.2 m
