I promise I will mark as brainiest and 5 stars and thanks a snake saw a hawk at height of 160 meter and hawk was flying at a speed of 24meters/minute to pounce on it if the hawk is launching vertically downwards according to the relation d=Vt+4.9t^{2} where d is the distance by meter, V is the launching speed in meter/minute and t is the time in minutes find the time the snake takes to escape before the hawk reaches it

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
