Q. 9

Solution:

Given,

Force = 7 kg.wt = 7 N

Mass = 9.8 kg

By applying the formula of Force

F = m × a

where, "m" indicates the mass, "F" indicates the force and "a" indicates the acceleration.

Force = Mass × Acceleration

F = m × a

Therefore, a = F / m

=> a = 70 N / 9.8 kg

=> a = 7.1428 m/s^2

Thus, the acceleration produced is 7.1428 m/s^2.

Q. 10

Solution:

Given,

Momentum = 50 kg m/s

Velocity = 5 m/s

By applying the formula of Momentum

Momentum = Mass × Velocity

p = m × v

where, "m" indicates the mass, "p" indicates the momentum and "v" indicates the velocity.

p = m × v

Therefore, m = p / v

=> m = p / v

=> m = 10 kg

Thus, the mass of the body is 10 kg.
