Answer:
Work done, W = 84.57 Joules
Explanation:
It is given that,
Mass of the wooden block, m = 2 kg
Tension force acting on the string, F = 30 N
Angle made by the block with the horizontal,
Distance covered by the block, d = 3 m
Let W is the work done by the tension force. It can be calculated as :
W = 84.57 Joules
So, the work done by the tension force is 84.57 Joules. Hence, this is the required solution.
Answer:
The speed of the car is 32.4m/s
Explanation:
1mi = 1600m
152mi = 243 200m
2hr 5min = 7200s + 300s
= 7500s
speed = distance/time
= 243200/7500
= 32.4m/s (3s.f)
