(A star if you answer this question) A school bus is traveling at 11.1 m/s and has a
12345 [234]

\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}

Actually Welcome to the Concept of the Kinematics in real world.

So, as given here, we have to find the Mass of the bus from the given momentum, so we get as,

P = m * V

momentum = mass * velocity

here, P= 152625 kgm/s and v= 11.1 m/s

so substituting we get as,

m = 152625 ÷ 11.1 => 13,750 kg

hence,the mass of the bus is 13,750 kg.

The spaceship Enterprise 1 is moving directly away from earth at a velocity that an earth-based observer measures to be 0.62c. A
podryga [215]

Answer:

The answer is "0.92 c"

Explanation:

v_1\ (earth) = 0.62 \ c \\\\v_2\ ( enterprise ) = -0.30

so,

v_2 \ (earth) = 0.62 \ c - (-0.30 \ c)  \\\\

               =  0.62 \ c +0.30 \ c\\\\= 0.92 \  c

An 835 kg dragster accelerates from rest to 110 km/h in 0.90 seconds.
sveticcg [70]

Answer

given,

mass of the dragster = 835 Kg

initial speed, u = 0 m/s

final speed, v = 110 km/h = 110 x 0.278 = 30.58 m/s

time, t = 0.90 s

a) Change in momentum

   Δ P = m v - m u

   Δ P = 835 x ( 30.58  - 0 )

   Δ P =  25534.3 kg.m/s

b) average force exerted on the car

    change in momentum = Force x time

            25534.3 = F x 0.9

              F = 28371.44 N

c) The exerted force is due to friction because the motion of the dragster is because of friction.
