A ball is dropped from a height of 20m and renounce with the velocity which is 3/4 of d velocity with which it hits the ground.
Mashutka [201]

Answer:

1.73 seconds

Explanation:

The velocity the ball first hits the ground with is:

v² = v₀² + 2aΔx

v² = (0 m/s)² + 2 (-10 m/s²) (-20 m)

v = -20 m/s

The velocity it rebounds with is 3/4 of that in the opposite direction, or 15 m/s.

The time it takes to return to the ground is:

Δx = v₀ t + ½ at²

0 = (15 m/s) t + ½ (-10 m/s²) t²

0 = t (15 − 5t²)

t = √3

t ≈ 1.73 seconds

Suppose that you lift four boxes individually, each at a constant velocity. The boxes have weights of 18 N, 6.0 N, 9.0 N, and 12
cricket20 [7]

Explanation:

It is known that the relation between work and force is as follows.

              w = F \times d cos (\theta)

where,    \theta = angle between the applied force and direction of movement of the object which is zero in this case. As, cos (0) = 1.

Therefore,    d = \frac{w}{F}

(i)   For w = 36 J, and F = 9 N then value of d will be as follows.

                    d = \frac{w}{F}

                       = \frac{36 J}{9 N}

                       = 4 m

(ii)  For w = 36 J, and F = 12 N then value of d will be as follows.

                    d = \frac{w}{F}

                       = \frac{36 J}{12 N}

                       = 3 m

(iii)  For w = 36 J, and F = 6 N then value of d will be as follows.

                    d = \frac{w}{F}

                       = \frac{36 J}{6 N}

                       = 6 m

(iv)  For w = 36 J, and F = 18 N then value of d will be as follows.

                    d = \frac{w}{F}

                       = \frac{36 J}{18 N}

                       = 2 m
