Find the change in the length of a second's pendulum, if the acceleration due to gravity change from`9.65m//s^2` to `9.8m//s^2`.

Acceleration due to gravity g=__________ m//s^2 .

A jeep moving at a speed of 50 km/hr reaches the foot of smooth incline where its engine is switched off. How much distance does the jeep go up the incline before coming to rest ? The inclination of the plane to the horizontal is 45^@ and the acceleration due to gravity at the place is 9.8m/s^2

A massless string passes over a frictionless pulley and carries two masses m_1 and m_2(m_1 > m_2) at it's ends. If g is the acceleration due to gravity, then the thrust on the pulley is (m_1>m_2) .

Find the velocity and acceleration at the end of 2 seconds of the particle moving according to the following rules. s = 3/2t + 1

A stone is dropped from the window of a train running at 50 (km)/(hr) . If the window is 1.5m above the ground, find the distance along the track which the stone moves before it strikes the ground. Acceleration towards the earth = 9.8 m /s^2 .
