Answer:
man upward acceleration is 0.14m/s^2
Explanation:
given data:
mass of man = 72 kg
downward force = 360 N
The mass of man of weight 72 kg is hang from two sections of rope, one section pf rope ties around man waist and other section is ties in man hands. when he pulls down the rope with 360 N force then each section of rope pulls with 360 N
we know that
Weight= mass × gravity= 72kg × 9.8 = 705.6N
Force = mass× acceleration
Force= -705.6 + (2 × 358) = 10.4 N

Answer:
The force exerted on truck A by truck B will definitely be greater than the magnitude of the force exerted on truck B by truck A
Explanation:
According to the concept of momentum
Momentum is the product of a body's mass and its velocity.
Yes both trucks are the same, but truck B is carrying a heavy load which gives it more momentum that A, actually momentum is a function of mass
Momentum M=mass(m) x velocity (v)
