If a motorbike of mass 150 kg moving with the speed of 36 km/hr produces
Aloiza [94]

Answer:

P = 7500 [W]

Explanation:

First We must use Newton's second law to find the force. Newton's Second Law tells us that the sum of forces on a body is equal to the product of mass by acceleration.

∑F = m*a

where:

m = mass = 150 [kg]

a = acceleration = 5 [m/s²]

F = 150*5\\F = 750 [N]

We know that the work is determined by multiplying the force by the distance, in this way the units of the work are [N*m] which corresponds to 1 Joule [J].

And the power is determined by dividing the work by the time, in this way we have that [J/s] corresponds to 1 [W].

We must convert the speed from kilometers per hour to meters per second.

36[km/hr]*1000[\frac{m}{1km}]*[\frac{1hr}{3600s} ]=10 [m/s]

P=F*v

where:

P = power [W]

F = force = 750 [N]

v = 10 [m/s]

P = 750*10\\P = 7500 [W]

A 10-m-long glider with a mass of 680 kg (including the passengers) is gliding horizontally through the air at 26 m/s when a 60
blagie [28]

Answer:

The glider’s speed after the skydiver lets go is 26 m/s

Explanation:

To calculate the glider’s speed just after the skydiver lets go, we will need to use the conservation of momentum

Mathematically;

mv = mv + mv

so 680 * 26 = (680-60)v + 60 * 26

17680 = 620v + 1560

17680-1560 = 620v

16120 = 620v

v = 16120/620

v = 26 m/s
