(1) [3 pts.] Little Graham is playing with a toy truck (mass m = 1.25 kg) on his grandma's rug. The net forward force on the truck (Graham's applied force and rug's friction combined) is 15.0 N. Neglect air resistance. Find the time the truck takes to increase its speed from 0.63 m/s to 4.41 m/s.

Step 1
We need to find the time it takes for the truck to increase its speed. We can use Newton's second law, $F = ma$, to find the acceleration of the truck. $F = 15.0 N$ $m = 1.25 kg$ $a = \frac{F}{m} = \frac{15.0 N}{1.25 kg} = 12.0 m/s^2$ Show more…

13. A block weighing 900 N is pushed along a surface. If it takes 69 N to get the block moving and 70 N to keep the block moving at a constant velocity, what are the coefficients of friction ÎĽs and ÎĽk? 14. An athlete runner starts at rest and accelerates forward, reaching a velocity of 12.00 m/s in 5.50 s. (a) What is her average acceleration? (b) What average force does the ground exert forward on the runner so that she achieves this acceleration? The player's mass is 69.0 kg, and air resistance is negligible. 15. A 6.50-kg model plane has a velocity of 6.900 m/s initially. It is accelerated at a constant rate for two seconds (5.00 s) after which it has a velocity of (9.6 m/s + 6.9 m/s). What is the magnitude of the resultant force acting on the helicopter during this time interval?
