Question

the weight of a body in water is 100N. the water exerted a buoyancy of 20N calcuate the weight of the body in air​

Answer 1

Answer:

9.

Two balls of equal masses unduguullo

1 collision with an i

tion increases fror

of restitution is

find the speed of each ball after impact in m/s.

Find the mar

10.

A body of mass 1 kg moving with velocity 1 m/s

stationary body. They are in contact for a

to F, linearly in 0.5 s and dec

of force Fo in newtons.

3 with velocity 1 m/s makes an elastic one dimensional collision,

hey are in contact for a brief period 1 s. Their force of interaction increa

and decreases linearly to zero in a further 0.5 s as shown in figure. Find +
