A car weighing 9800 N travels at 30 m/s. What braking force brings it to rest in 100m? In 10 m?

Svetach [21]

As per kinematics equation we know that

final speed of the car = 0 m/s

initial speed is given as 30 m/s

distance moved = 100 m

now we have

$v_f^2 - v_i^2 = 2 a d$

$0 - 30^2 = 2(a)(100)$

$a = - 4.5 m/s^2$

now braking force is given as

$F = ma$

now for mass we know that the weight of car is

$W = mg = 9800 N$

so mass of car is

$m = 1000 kg$

now we have

$F = 1000(4.5) = 4500 N$

Part b)

Again we have

final speed of the car = 0 m/s

initial speed is given as 30 m/s

distance moved = 10 m

now we have

$v_f^2 - v_i^2 = 2 a d$

$0 - 30^2 = 2(a)(10)$

$a = - 45 m/s^2$

now braking force is given as

$F = ma$

mass of car is

$m = 1000 kg$

now we have

$F = 1000(45) = 45000 N$

An electric heater is rated at 1500 W. If the heater is rated as 80% efficient, calculate the output

Nadya [2.5K]

Answer:

Power = 1200 [W].

Explanation:

The efficiency of an electrical equipment is defined as the relationship between the power realized, over the power that is consumed. For this case, they give us the data of consumed power and efficiency in this way we can calculate the power that the equipment performs.

$Efficency=\frac{Power_{done}}{P_{consumed}}\\0.8 = \frac{Power_{done}}{1500} \\Power_{done}=1500*0.8\\Power_{done} = 1200 [W]$

This means that of the 1500 [W], 1200 [W] are actually used to get the job done. This is established by means of the first law of thermodynamics.
