Since the mass is 5 grams the acceleration is: 4000 m/s^2

But if the mass is 5 Kilograms the acceleration is: 4 m/s^2

Vanyuwa [196]

Answer:

9800 m

Explanation:

During acceleration, given:

v₀ = 0 m/s

a = 39.2 m/s²

t = 10.0 s

Find: v and Δy

v = at + v₀

v = (39.2 m/s²) (10.0 s) + 0 m/s

v = 392 m/s

Δy = v₀ t + ½ at²

Δy = (0 m/s) (10.0 s) + ½ (39.2 m/s²) (10.0 s)²

Δy = 1960 m

During free fall, given:

v₀ = 392 m/s

v = 0 m/s

a = -9.8 m/s²

Find: Δy

v² = v₀² + 2aΔy

(0 m/s)² = (392 m/s)² + 2 (-9.8 m/s²) Δy

Δy = 7840 m

Therefore, h = 1960 m + 7840 m = 9800 m.

How does changing the time affect work? How about power?

Julli [10]

Work = Force × Distance
Distance = Velocity÷Time
Power = work × Time

Time is directly related to distance which is in the work equation.

Time is directly related to the power equation due to the power equation itself.

If time changed at all it would change the result of power and work both.

Hope that helped!!!

a 507-kg car is in a collision with a 948-kg car. during the collision, the car applies a maximum force of 7,849 n on the truck.

katrin [286]

In a collision of 507 kg car with 948 kg truck, the maximum force that the truck applies on the car is 4208 N

Referring to the free-body diagram of each object:

Forces applied on truck

- Force from car to truck (Fct)

- Static friction force (Ft)

The net force = 0, hence,

Fct = Ft

7849 = μ . 948 . 10

Where μ is the coefficient of static friction

Hence,

μ = 7849 / 9480 = 0.83

This coefficient of static friction is assumed to be the same for the static friction force of truck and car.

Forces applied on car

- Force from truck to car (Ftc)

- Static friction force (Fc)

The net force = 0, hence,

Ftc = Fc

Ftc = μ . 507 . 10 = 0.83 . 507 . 10 = 4208 N
