using this information: if an object is thrown straight up into the air from the height H feet per second then at time tseconds the height of the object is 16.1t^2 +Vt+ H feet. This formula uses only gravitational force, ignoring

Question: Object A is moving at a maximum speed of 6m/s towards Object B. At 50 m away Object B accelerates from the approaching Object A at 0.3m/s^2. Does Object A catch up to Object B and if yes when? I don't know how to answer

An object is thrown upwards and after 2 seconds is 78 m above where it was initially thrown. Assume no air resistance, and determine the initial speed the object was thrown at.

if an object with mass m is dropped from rest, one model for its speed v after t seconds, taking air resistance into account is v= mg/c(1e^(ct/m)) where g is the acceleration due to gravity and c is a positive constant

An object is dropped from a bridge.A second object is thrown downwards 2.00s later.They both reach the water 35.0m below at the same instant.What is the initial speed of the second object? I will be very grateful if someone could

An object is thrown straight upwards from the ground at 28 m/s. Due to air resistance (a nonconservative force), the object loses 31.4 percent of its initial energy during its trip to reach maximum height. How much higher does
