cindy threw a ball with Kinetic energy of 3.5 ana a velocity of 17 m/s. What is the mass of the ball?
abruzzese [7]
  • K.E=3.5J
  • Velocity=17m/s
  • Mass be m

\\ \sf\Rrightarrow K.E=\dfrac{1}{2}mv^2

\\ \sf\Rrightarrow 3.5=\dfrac{1}{2}m(17)^2

\\ \sf\Rrightarrow 7=289m

\\ \sf\Rrightarrow m=\dfrac{7}{289}

\\ \sf\Rrightarrow m=0.024kg

Answer:

It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation).

A truck moving at 20 mph shoots a soccer ball at 20 mph in the opposite direction. How fast is the soccer ball moving? Explain
Brrunno [24]

Answer:

Speed of the soccer ball with respect to ground is ZERO

Explanation:

As we know that truck is moving with speed 20 mph

Now a soccer ball is shoot from truck with respect to the motion of truck in opposite direction

The relative speed of the soccer ball is

v_{bt} = 20 mph

now we know that

v_{bt} = v_b - v_t

so we have

-20 mph = v_b - 20

so we have

v_b = 0
