Answer:24888.8g
Explanation: 28cupcakes calls 360g
32 cupcakes calls ???
28x32=896 cupcakes
896/360= 2.4888888g
In four decimal place = 24888.8grams
Answer:
change in KE = -12.95 Btu
Explanation:
given data
mass = 3000-lbm
velocity of vehicle initial vi = 10 mph = 14ft/s
velocity of vehicle final vf = 0 mph = 0 ft/s
solution
as here for crumple zone to protected zone it will absorb kinetic energy
so change in KE is related here initial and final velocity that is
change in KE = 0.5 × m × (vf² - vi² ) .................1
put here value and we get
change in KE = 0.5 × 3000 × (0² - 14.7² )
change in KE = -324135 ×
*
change in KE = -12.95 Btu
Answer
given,
mass of the stick = 290 grams = 0.29 Kg
Force on the stick on one side = F = 9 N
force acting perpendicular to stick.
magnitude of acceleration
rate of change of angular momentum is equal to Force
rate of change of angular momentum = 9 N
F = m a


a = 31.034 m/s²
Direction of motion will in the direction of force application or in the direction of change of velocity
