A hot air balloon accelerates upwards from the ground at 0.05m/s2. It maintains this acceleration for the first 40 seconds of its flight. One sandbag is then released which increases the acceleration of the balloon to 0.08m/s2
1. What is the speed of the balloon 40 seconds after it has been released from the ground?
2. What is the speed of the balloon 20 seconds after the sandbag has been released
