Two blocks with masses m1=3 kg and m2=4 kg are touching each other on a fricionless surface. If a force of 5 N is applied on m1 as shown in figure. The acceleration of each block is
A body hangs from a spring balance supported from the from the ceiling of an elevator. If the elevator has an upward acceleration of 2.5m/s2 and the balance reads 50N,what is the true weight of the body?
The acceleration of block of mass 2 kg and 4 kg are respectively (pulleys and Threads are massless) (g=10 m/s2).
a) a1 = 5 m/s2 , a2 = 2.5 m/s2
b) a1 = a2 = 0
c) a1 = a2 = 20/6 m/s2
d) a1 = 20 m/s2 , a2 = 5 m/s2
