A body falls freely from rest on Earth (g= - 10 m/s) 1. The displacement at t = 3 sis -45 m 2. The time for it to reach a speed of 25 m/s is I $ 3. The time to fall 320 m is 8 s. 4. The speed after falling 80 m is m/s. An object is thrown downward with an initial velocity of -20 m/s on Earth 5. The acceleration of the object after 1 s is -10 m m 6. The object's displacement after 4 sis -120 7. The time required to reach a speed of 50 misis -2.5 8. The velocity after falling 105.8 mis mis
