After riding his bike for 5 seconds and accelerating at 1.2 m/s2, Bob was riding 8 m/s at the star of his trip. What velocity was Bob riding when he finished his trip?

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)

Avehicle accelerates from 0 to 30 m/s in 10 seconds on a straight road

Agirl throws a ball. if the ball's acceleration is 12 m/sec/sec and its mass is 0.5 kg, how much force did the girl apply to the ball?
