A spring-mass system oacmates hi a car. it the car accelerates on a horizontal road,

(a) : Both the scales read Mkg each.

(d) : Acceleration of the system a = F/(m + M) Force on block of mass m = ma = mF/(m + M).

(d) the road. Explanation: The car pushes the ground in the backward direction and according to the third law of motion, reaction force of the ground in the forward direction acts on...

From where does the 2Π√l/g^2+a• come from ?

(a) The volume of wooden block = 0.5/800 m³  =0.000625 m³  The force of buoyancy =0.000625*1000 kg =0.625 kg  The Net force on the block in the water =0.625-0.500 kg-weight  =0.125*10 N {Taking g =...

Correct option: (d) the road. Explanation: Car moves on the road due to a reactional force of the road on the car.

(a) the spring was initially compressed by a distance! and was finally in its natural length  (b) it was initially streched by a distance x and was in its natural length  Explanation:  Since...

(B) Car is in motion

(1) The reading of the spring balance is 24N. Explanation: When lift is stationary,  W1 = mg When the lift descends with acceleration a, W2 = m(g – a) W2/W1 = (g – a)/g = (9.8 - 5)/9.8 = 4.8/9.8 W2 = W1 x (4.8/9.8) = 49 x (4.8/9.8) = 24 N
