a force of 4N gives the mass of m1, an acceleration of 26m/s^2 and a mass m2, an acceleration of 30m/s^2.What acceleration would it give if both the masses are tied together?
frnds please answer this question as soon as possible.
Answers
Answer:
From Newton's second law of motion,the applied force is directly proportional to the acceleration produced orF=ma.
The unit of force is Newton in SI
denoted by the symbol N.
Forces acting on mass m1 with acceleration a1 and mass m2 with acceleration a2 are as given below:
m1=F/a1=4/26kg
m2=F/a2=4/30Kg
M=(4/26+4/30)kg=56/195kg
Acceleration produced in M( when two masses are tied together)
a=F/M=4/56/195=4*195/56
Answer:
195/14 m/s²
Explanation:
Using, F = mass x acceleration
For m1,
=> 4 = m1 x 26 m/s² => m1 = 4/26 kg
For m2,
=> 4 = m2 x 30 m/s² => m2 = 4/30 kg
If m1 and m2 are joined.
total mass = m1 + m2 & let acceleration be 'a'
=> 4 = a(m1 + m2)
=> 4 = a(4/26 + 4/30)
=> 4 = 4a(1/26 + 1/30)
=> 1 = a(1/26 + 1/30)
=> 1 = a(26+30)/(26*30)
=> 1 = a(56)/(780)
=> 780/56 = a
=> 195/14 = a
