A 50 kg bicyclist, traveling at a speed of 12 m/s, applies the brakes, slowing her speed to 3 m/s.
Bezzdna [24]

a) Work done = Net Kinetic Energy

= 1/2 x 50 kg x ((12m/s)^2 - (3m/s)^2)

= 0.5 x 50 Kg x (144 -9)(m/s)^2

= 3375 Kg (m/s)^2

b) Force = mxa

a = 120 N/50 Kg = 2.4 m/s^2

Using newtons third law of motion, we get-

V^2 - U^2 = 2 x a x S

S= (12^2-3^2)m^2/s^2/(2 x 2.4 m/s^2)

= 28.125 m

A rescue airplane is diving at an angle of 37o below the horizontal with a speed of 250 m/s. It releases a survival package when
igomit [66]

Answer:

796.2 m.

Explanation:

A sketch of the given question forms a right angled triangle with two given sides and a non included angle. Applying the appropriate trigonometric function, we have;

Tan θ = \frac{opposite}{adjacent}

Let the horizontal distance required be represented by x, so that;

Tan 37^{o} = \frac{600}{x}

0.7536 = \frac{600}{x}

⇒ x = \frac{600}{0.7536}

      = 796.1783

x = 796.2 m

Thus, the horizontal distance of the point of impact is 796.2 m.

Under what conditions does the magnitude of the average velocity equal the average speed?
Dmitry [639]
So when the body moves in a straight line the average velocity is equal to the average speed. average velocity would be equal to average speed when the total distance travelled equals the net displacement of a particle. this happens when a particle moves along a straight line in a fixed direction.
