A pasta was thrown from the ground surface, with a velocity of 5 m/sec and it got stuck on roof. Find the height between ground and roof.

Which of the following relationships is correct?

Find radius of a planet if its mass is 5.96 × 12²⁴ kg.

(where g = 9.8 m/sec², G = 6.67 × 10-11 Nm²/ Kg²)

The mass of an object is 5 kg and acceleration produced is 3 m/sec² from first second to sixth second. Find change in momentum.

Which of the following options is correct that truly tells about the properties of mass and weight?

(1) It is a scalar quantity.
(2) It is the force with which earth attracts the body.
(3) It is measured by physical balance.
(4) It is measured by beam balance.

A train of mass 3 × 10⁷ kg initially at rest is pulled by a force of 5 × 10⁴ N through a distance of 3 m. Assume air resistance to be negligible, find speed of train.
